Cross beak color and feather color.
(Score for Question 1: Click or tap here to enter text. of 2 points)
Cross one parent that is heterozygous for both beak color and feather color with a parent that is h-o-m-o-zygous for both recessive traits. What are the genotypes of the parents? (Hint: Recall that the P generation includes a heterozygous parent with dominant traits and a h-o-m-o-zygous parent with recessive traits.)
Assume the following F1 generation:
YyBb: 420
Yybb: 80
yyBb: 80
yybb: 420

YyBB420
YyBb420

How far apart are L and B?

L and B are 4 units apart because they make up 4 % of the total recombinant types.
