In a dihybrid cross of two heterozygous individuals, you expect a 9:3:3:1 phenotypic ratio in the offspring, but observe a ratio
almond37 [142]

Answer:

e. Epistatic interaction of the two genes

Explanation:

The 9:7 ratio is typical of the Duplicate Recessive Epistasis.

The expected phenotypic ratiio of the offsrping of a dihybrid cross is:

9 A_B_

3 A_bb

3 aaB_

1 aabb

In the Duplicate Recessive Epistasis, the A_bb, aaB_ and aabb individuals all have the same phenotype, making for the ratio 9:7. What those three genotypes have in common is that in all of them at least one of the two genes  is homozygous recessive (either <em>aa</em> or <em>bb</em>).

This usually happens one the products of genes A and B are enzymes of the same metabolic pathway.

Whenever both A and B are present, the pathway can produce the final product and a certain phenotype. However, if any of the dominant alleles is missing, the enzyme is not produced and therefore the final product of pathway is not produced, giving the other phenotype.

Answer:

In order to survive.

Explanation:

A normally aquatic species adapt to the supralittoral fringe in order to survive in that environment. Supralittoral zone also referred to the area on coastlines and estuaries, that is regularly splashed, but not submerged by ocean water. This environment is different for the marine organisms that causes adverse effect on the marine organisms but these marine animals has the ability to adapt that environment by using certain mechanism in order to survive and easily reproduce in that environment.
