This is normally accomplished through methylation of a cytosine:

a. paternal effect b. imprinting c. epistasis d. maternal inheritance e. aromatase

Expert Solution

Imprinting

People inherit two copies of their genes—one from their mother and one from their father.
Usually both copies of each gene are active
In some times , only one of the two copies is normally turned on. Which copy is active depends on the parent of origin
some genes are normally active only when they are inherited from a person’s father;
others are active only when inherited from a person’s mother.

This phenomenon is known as genomic imprinting.

methylation, is a chemical reaction that attaches small molecules called methyl groups to certain segments of DNA.
Thesemolecules identify which copy of a gene was inherited from the mother and which was inherited from the father.
The addition and removal of methyl groups can be used to control the activity of genes.

Epistasis ,when one Gene locus mask or modify the genotype of second locus
Paternal effect mutations are defined as mutations that when present in males affect the development of their offsping
Aromatase is enzyme responsible for conversion of androgen to estrogen and testosterone to estradiol
Maternal inheritance is a type of heredity in which the characters are influemced more by egg than sperm.
