Answer #1

Answer 1 :-

X- dominant transmission pattern forms here. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons (no male-to-male transmission).

Answer 2 :-

Polygenic inheritance refers to the expression of traits controlled by two or more genes and environmental interactions. Polygenic traits do not follow mendelian patterns of dominance and recessiveness.

Special circumstance of epistasis is that it occurs when two or more different gene loci contribute to the same phenotype.

A woman (Tina) has a certain genetic condition (is affected). She goes to a genetic counselor to learn about the inheritance pattern of the condition and to ascertain the chance that she might pass it to her offspring. The following is the information she gives the Genetic Counselor.
