based on mendel's laws you've learned so far, why didn't the allele for yellow color show in the f1 generation?

Answers

Answer 1

Yellow color is a recessive trait, so it would only show in the F1 generation if both parents had the allele for yellow color.

What is Mendel's laws?

Mendel's laws are the foundation of genetics. They were first proposed by the Austrian monk and scientist Gregor Mendel in 1865. Mendel's laws describe how genetic traits are passed from parent to offspring.

The first law, known as the law of segregation, states that for each inherited trait, an organism receives one variant from each of its parents, and that these variants separate during the formation of gametes, or sex cells.

The second law, the law of independent assortment, states that when different traits are inherited, the separation of one trait does not affect the separation of another. This means that the inheritance of one trait does not influence the inheritance of another trait. Together, these laws form the basis for understanding the transmission and expression of genetic traits.

if 1 out of every 250,000 people have disease x, a nonlethal autosomal recessive disorder, what is the approximate carrier frequency of this disease?

Answers

q2 = The disease's occurrence

p = 1 - q = 499/500 = 1 carrier frequencies = 2pq = 2(1/500)(1) = 1/250; q2 = 1 in 250,000.

It is straightforward to determine the carrier frequency to use some very basic algebra if the prevalence of such an autosomal recessive disease was known.

For instance, if the disease incidence is 1 in 10,000.

q2 = 1/10000 &

q = 1/100 .

Since p + q = 1, p is equal to 99/100.

then, it is possible to determine the carrier frequency as

Answers

Answer:

The algae would decrease.

Explanation:

As the number of steelhead fish increases, they will consume more predatory insects, which in turn would consume more midge larvae. As a result, there would be fewer midge larvae to feed on the algae, leading to a decrease in the amount of algae in the stream.

What is directional and stabilizing selection?

Answers

Directional selection and stabilizing selection are two types of natural selection that can lead to changes in the traits of a population over time.

Directional selection is a type of natural selection that occurs when the environment favors individuals with a certain trait, while selecting against individuals without that trait stabilizing selection. This can lead to a shift in the distribution of traits within a population over time, in the direction that increases the population's chances of survival. Stabilizing selection, on the other hand, directional selection is a type of natural selection that occurs when the environment favors individuals with intermediate traits, directional selection shifts the trait distribution towards one side, while stabilizing selection maintains the norm or the average of a certain trait within a population and reduces the genetic variation.

An ionic bond will form between one positive ion and:
O A. one negative ion.
OB. any other ion.
OC. another positive ion.
OD. one neutral atom.

Answers

Option A is the appropriate response, An ionic bond will form between one positive ion and one negative ion.

What do ions do?

An atom or molecule is called a "ion" when the proton and electron counts are out of balance, which generates a net electric charge.

How do you figure it out?

Ionic connections are formed when a positive ion, also known as a cation, and a negative ion combine (also known as an anion). This link is formed by the transfer of an electron from one element to another, resulting in the production of a positive and a negative ion. Positive and negative ions are drawn to one another because of their opposing charges, which results in the formation of an ionic bond.

The resistance between two positive ions prevents them from forming an ionic bond. Similar to this, the absence of any charges that may attract two neutral atoms together prevents them from forming an ionic bond.

Ionic bonds are important for the production of many natural substances, such as salts and minerals, as well as for many biological processes.

Answers

Trees growing tall indicates an abundance of sunlight in the biome. The correct response is that the biome receives abundant sunlight.

Plant growth is dependent on various factors like sunlight, water and temperature, and nutrients from the soil. The absence or extreme of any can be detrimental to growth.

Plants like other organisms require sunlight as they develop. Abundance of sunlight promotes higher rates of photosynthesis, providing an opportunity for increased growth of the trees.

Cold temperatures year round inhibit the growth of the trees and lead to stunted growth. This is why trees in tropical regions are taller than the trees in tundra and taiga regions.

As the plant grows it requires water. Water is required for the conduction of nutrients, in photosynthesis and also in the cells to maintain their viability. Limited rainfall would make the trees be able to support a smaller biomass, that is, they would not grow very tall.

If the soil is not fertile it cannot support the growth of trees, as trees grow they require nutrients majorly NPK and other macro and micronutrients. In fertile soil leads to stunted growth.

Considering all the nutrients required, limitation rain and nutrients stunt the growth same is true for the trees facing extreme cold temperatures year-long. Abundance of sunlight with ample nutrients and optimum conditions does however lead to taller growth in trees.

An illustration of how living things react to their surroundings is when some North American birds migrate south for the winter.

Every living thing has the capacity to react to environmental stimuli. Living organisms, for instance, react to alterations in light, heat, sound, and chemical and mechanical touch. Organisms have sensory organs like eyes, hearing, and taste buds that they can use to detect inputs.

An organism must coordinate its reactions in order to react to environmental changes effectively. An organism's functions are coordinated by a network of neurons and several hormone-like chemical regulators. Several effectors, including muscles and glands, are used by the organism to react to the stimuli. In the process, energy is often used.

As the environment around them changes, organisms adapt their behavior. An organism, for instance, might move in response to its surroundings. Such reactions take the form of distinct patterns that make up an organism's behavior. A stone rolling down a hill is not the same as an animal responding to a stimulus; the behavior is active and not passive. Nonliving things do not exhibit responsiveness, only living things do.
