Question

In Mirabilis (Four-O’ clock plant), two genes, Y and R,affect flower colors. Neither is
completely dominant and they interact with each other to produce 7flower colors-
RRYY = crimson YyRR = magenta YYRr = Orange-red YyRr =magenta-rose
Yyrr = yellow Yyrr = pale yellow yyRR, yyRr and yyrr = white
Two four-O’ clock plants were crossed and gave the followingoffspring-
1/8 crimson, 1/8 orange-red, 1/4 magenta, 1/4 magenta-rose, 1/4white.
What are the genotypes and flower colors of the 2 parent plants?

Explanation / Answer

The genotypes for the two parents are YyRr (magenta-rose) andYyRR(magenta) you end with a 1:2:2:2:1 phenotype if you do apunnet square which gives you the proper ratios in the aboveproblem. You just have two different white genotypes but they stilldisplay the correct phenotype. PLEASE RATE ME
