Question

For each of the diploid genotypes presented below, determine the genetic make up for all of the possible haploid gametes.

Answer 1

Answer:

a. R and r

b. RY, Ry, rY, and ry

c. rY and ry

d. RY and rY

e. RYB, RYb, RyB, Ryb, rYB, rYb, ryB, and ryb

Explanation:

According to Mendelian principle, a gene is made up of 2 alleles and these alleles segregate during gametes formation to randomly unite back during fertilization. Hence;

Rr can only segregate as R and r

RrYy can segregate as RY, Ry, rY, and ry

rrYy can only segregate as rY and ry

RrYY can only segregate as RY and rY

RrYyBb can segregate as RYB, RYb, RyB, Ryb, rYB, rYb, ryB, and ryb
