The two features of two people regulated by two different genes are called a dihybrid cross. A dihybrid cross is made up of two people who have two features that are regulated by two different genes. Gregor Mendel's observation of pea plants that were either round or wrinkled, yellow or green, gave rise to the concept of a dihybrid cross. When  On the cross of two heterozygous people we can predict the genotypic and phenotypic ratios  of the offspring’s . Crossing heterozygous parents would result in an estimated phenotypic ratio of 9:3:3:1, meaning that 9/16 of the individuals have the dominant phenotype for both traits, 3/16 have the dominant phenotype for one trait, 3/16 have the dominant phenotype for the other trait, and 1/16 have the recessive phenotype for both traits,Only applies to sexually reproducing organisms like angiosperms. The components of the predicted phenotypic ratio of 9:3:3:1 are as follows:

In the movement of small molecules across a lipid bilayer the permeability coefficient can be correlated with the solubility of the molecule in a nonpolar solvent.

Non-polar molecules dissolve in the phospholipid region of the cell membrane and pass without the need for additional protein transporters. Small hydrophobic molecules and gases such as oxygen and carbon dioxide pass quickly through the membrane. Small polar molecules like water and ethanol can also pass through the membrane, but more slowly.

A conformational change in the channel moves the second-site potassium ion away from the protein. When a second potassium ion binds to the first site, electrostatic repulsion occurs and helps dislodge the potassium ion from the second site. Permeability decreases with charged or larger molecules. The structural features of these molecules do not affect membrane fluidity. Expression of permeability of molecules across membranes based on molecular size and charge.

The temperature of the gas sample at the new volume and pressure must be 65.74 T

Pressure is force (in newtons, N) divided by the area ( in square meters, m2 ) over which it acts (P = F/A). Volume is the amount of space is taken up by an object or, in our case, a parcel of gas.

The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules (Avogadro's law).

Hence, for a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.

They explain the variety in human height, form, behavior, skin color, hair color, and susceptibility to disease that we observe. Other species' individuals differ from one another in terms of both appearance and behavior.

Genetic diversity is advantageous because it aids in the evolution of populations. The next generation inherits variations that assist an organism live and procreate.
