4. A woman who is heterozygous for freckles and a carrier for PKU disease marries a
man who is also heterozygous for freckles and a carrier for PKU disease. List the
probability for each of the four possible phenotypes (not genotypes) in their offspring.
Answer:
Freckles, no PKU- 9/16
Freckles, PKU- 3/16
No freckles, no PKU- 3/16
No freckles, PKU- 1/16
Explanation:
This question involve two distinct genes; one coding for possession or not of freckles and the other for PKU disease in humans. Allele for freckles (F) and no PKU (P) are dominant over the alleles for no freckles (f) and PKU (p) respectively.
N.B: Possession of freckles is a dominant trait i.e. FF and Ff possess freckles
If a woman who is heterozygous for freckles and a carrier for PKU disease (FfPp) marries a man who is also heterozygous for freckles and a carrier for PKU disease (FfPp), they produce the following gametes: FP, Fp, fP, and fp
Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
Freckles, no PKU (F_P_) - 9/16
Freckles, PKU (F_pp) - 3/16
No freckles, no PKU (ffP_) - 3/16
No freckles, PKU (ffpp) - 1/16
The possible phenotypes of the offspring with their probabilities are:
Freckles and PKU = 3/4 x 1/4 = 3/16Freckles and no PKU = 3/4 x 3/4 = 9/16No freckles and PKU = 1/4 x 1/4 = 1/16No freckles and no PKU = 1/4 x 3/4 = 3/16Each of the traits would be independently inherited:
Freckles are autosomal dominant traits. Assuming the allele for freckles is A, a heterozygous individual will have the genotype Aa.
Aa x Aa
AA Aa Aa aa
Probability of having freckles = 3/4
Probability of not having freckles = 1/4
PKU is an autosomal recessive trait. Assuming the allele to be b, heterozygous individuals will have the genotype Bb.
Bb x Bb
BB Bb Bb bb
Probability of having PKU = 1/4
Probability of not having PKU = 3/4
The four possible phenotypes with their probabilities are:
Freckles and PKU = 3/4 x 1/4 = 3/16Freckles and no PKU = 3/4 x 3/4 = 9/16No freckles and PKU = 1/4 x 1/4 = 1/16No freckles and no PKU = 1/4 x 3/4 = 3/16More on dihybrid crosses can be found here: https://brainly.com/question/1185199?

Cytokinesis is the process of division of cytoplasm. The correct answer is cytokinesis.
The primary method of reproduction for unicellular organisms, cytokinesis also occurs during the growth and repair of tissues in higher plants and animals, as well as during the development of the embryo. Whether in mitosis or meiosis, it typically happens after nuclear doubling. Prokaryotes primarily reproduce by binary fission, in which the mother cell grows until it physically splits into two identical daughter cells through a process called cytokinesis.
Actin and myosin, the proteins involved in muscle contraction and other types of cell movement, form a ring around the cell to constrict it, causing cytokinesis to occur in animal cells. The formation of a new cell wall, known as the cell plate, between the two daughter cells divides the cytoplasm in plant cells. Following the division of the daughter cells, cellulose synthesis starts, and the cell plate develops into the primary cell wall.
Therefore, in any cell the cytoplasm, divides by cytokinesis. The correct answer is option c i.e. cytokinesis.

Diffusion is movement of a molecule from an area of higher concentration to an area of lower concentration. True or false
Answer:
THIS IS TRUE
Explanation:
It is the area of higher concertation to an area lower concertation
True: Diffusion involves the movement of a molecule from an area of higher concentration to an area of lower concentration.
Diffusion can be defined as the movement of gas molecules from an area (region) of higher concentration to an area (region) of lower concentration, until an equilibrium is attained (reached) within the system.
This ultimately implies that, gas molecules generally move from higher concentration areas to lower concentration areas during diffusion.
In conclusion, diffusion makes it possible for gas molecules to move from an area (region) of higher concentration to an area (region) of lower concentration.

Cohesin protein. Select all that apply. Select all that apply. It comprises filaments in mitotic and meiotic spindles. It prevents sister chromatid separation until anaphase of mitosis or anaphase II or meiosis. It is required for the segregation of chromosomes during anaphase of mitosis or meiosis. It is important for maintaining homologous chromosome pairing and plays a role in recombination. It holds sister chromatids together after chromosome replication.
Answer:
It prevents sister chromatid separation until anaphase of mitosis or anaphase II of meiosisIt is important for maintaining homologous chromosome pairing and plays a role in recombination.It holds sister chromatids together after chromosome replication.Explanation:
Cohesin proteins are many protein subunits united and forming a complex that plays an important role in mitosis and meiosis. These complexes have many functions and are involved in DNI repairing or genetic expression, among others. But one of the most known functions is the one of keeping sister chromatids together during cellular division.
This function can be accomplished since the S phase of cellular division when chromosomes are replicated. The two new copies must stay together during the G2 phase and the cohesin proteins are the ones in charge of doing so until it is needed. During the G2 phase of mitosis, sister chromatids are held together until they reach the Anaphase, during which other enzymes are activated to break the bonds and separate the chromatids. During the G2 phase of meiosis, sister chromatids and homologous chromosomes are held together by the cohesin proteins. Homologous chromosomes must be together until crossing over is completed, and cohesin proteins play an important role in making in possible. After the firsts stages of meiosis, sister Chromatids get completely separated in Anaphase II. During this phase it occurs the same as in mitosis, bonds break and chromatids get separated and go forward each cellular pole.Statements that are correct as regards Cohesin protein are,:
It prevents sister chromatid separation until anaphase of mitosis or anaphase II of meiosis
It is important for maintaining homologous chromosome pairing and plays a role in recombination.
It holds sister chromatids together after chromosome replication.
Cohesin can be regarded as a protein complex which brings about mediation of sister chromatid cohesion as well as as homologous recombination, and DNA looping. It usually holds sister chromatids together when chromosome replication has been done.Therefore, Cohesin is essential in maintaining homologous chromosome pairing.

In this activity, you will research the genetic diversity in two fish variants. The Mexican tetra (Astyanax mexicanus) has two notable variations: the surface variety and the blind cave fish variety. In this activity, you’ll use credible websites to find the following information about these two fish:
What type of habitat does each fish live in?
How do their physical characteristics differ?
How are they similar?
Can the two types mate with each other?
Why are their characteristics advantageous to their environments?
When you’ve found the information, answer the following questions.
Part A :
What are the similarities and differences between the two fish varieties?
Part B:
Do you think these fish are an example of natural selection among two populations of the same species? Explain your answer.
Part C:
Explain how the characteristics of the two types of fish relate to the genetic diversity of the species.
Answer:
Part A-One of the variations have eyes as well as some pigmentation on them. They live near the surface of the water. The other variation does not have eyes and are often albinos. I found that these fish live in deep, dark caves.
Part B-Yes. I think that these fish are an example of natural selection. The blind fish live in caves and eyes take up energy that could be used somewhere else in the fish. So, they developed into fish with no eyes, allowing them to function more efficiently.
Part C- As a species, they have genetic diversity because the two populations have separate genes. The two fish types developed different traits because of their separate habitats.

A medicine to remove the redness in eyes was tested in a group of 100 students. Each student took either the medicine or a placebo in both eyes. The participants were given some free time after receiving their drops. The researcher did not keep track of what they did in that free time. It turns out that many of the people receiving the medicine spent their time outside and many of the people receiving the placebo spent their time inside. The results may now be biased because the variable location (inside vs. outside) is now a/an ____ variable.
Answer:
Independent variable
Explanation:
In a scientific experiment, an independent variable is that variable which the experimenter changes or manipulates in order to effect an outcome. Only one independent variable should be tested at a time in a good experiment, all other variables should be kept constant. The initial independent variable in this experiment is TYPE OF SUBSTANCE put in the students' eyes.
However, according to the question, the researcher did not keep track of what they did in that free time. Hence, many of the people receiving the medicine spent their time outside and many of the people receiving the placebo spent their time inside. The location of every student should be a CONSTANT VARIABLE i.e. same for all students but now it has become an INDEPENDENT VARIABLE because it has been changed.

Explanation:
because of the temperature
Temperature in degrees Fahrenheit can be converted to Celsius by first subtracting 32, then dividing by 1.8. What is the Celsius temperature outside on a warm day 100.
What is temperature?
Temperature is a unit used to describe hotness or coldness. It can be stated in terms of any number of arbitrary scales and shows the direction in which heat energy will naturally flow, i.e., from a hotter body to a colder body (one at a lower temperature).
Temperature is not the same as the energy of a thermodynamic system; for instance, an iceberg has a significantly larger total heat energy than a match, despite the fact that a match is burning at a much higher temperature.
As opposed to extensive characteristics, like mass or volume, temperature is referred to as an intense property—one that is independent of the quantity of matter being considered—along with pressure, density, and other comparable properties.
Therefore, Temperature in degrees Fahrenheit can be converted to Celsius by first subtracting 32, then dividing by 1.8. What is the Celsius temperature outside on a warm day 100.
