Answer:
<em>a) Alleles at one locus can hide or mask the effect of alleles at another locus </em>
Explanation:
Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.
Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". Epistatic genes might be either recessive or dominant. When the epistatic gene is recessive, the interaction is known as "recessive epistasis". While when the epistatic gene is dominant, the interaction is known as "dominant epistasis"
Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.
A mutation is a change in a DNA sequence brought about either by a mistake made when the DNA is copied or through chemical damage. Regions of the genome (called genes) provide instructions for creation of protein molecules, which perform most of the important jobs in cells. Certain types of mutations are silent and have no effect, but others affect protein production in a variety of ways.
Answer is: pH is an important quantity that reflects the chemical conditions of a solution. The pH can control the availability of nutrients, biological functions, microbial activity, and the behavior of chemicals.
