In humans, some forms of myopia dominate normal vision, and brown eye color dominates blue.

In humans, some forms of myopia dominate normal vision, and brown eye color dominates blue. The genes of these traits are on different chromosomes. What offspring can be expected from a marriage of a short-sighted brown-eyed man with a blue-eyed woman who has normal vision? Identify all possible genotypes of parents and offspring

Given: A-myopia, a-normal vision, B-brown eyes, B-blue eyes. Characteristic inheritance is independent. Find: F1, P-?
Decision,
There can be four options (depending on the genotype of the father)
Option 1:
P: AABB x aabb
G: AB and ab
Fl: AaBb – myopia, brown eyes.
Option 2:
P: AABb x aabb
G: AB, AB and AB
F1; AaBb – myopia, brown eyes; Aabb – myopia, pigeon eyes;
Option 3;
R; AaBB x aabb G: AB, aB and ab
F1: AaBb – myopia, brown eyes; aaBb – normal vision, brown eyes;
Option 4:
R: AaBb x aabb
G: AB, AB, AB, AB and AB
Fl; AaBv – myopia, brown eyes; Aabb – myopia, blue eyes; aaBb – normal vision, brown eyes, aabb – normal vision, blue eyes.
