100, 75, 50, or 25%

A red snapdragon is crossed with a white snapdragon. All the offspring are pink. The pink snapdragons?
50%





Rr + Rr =%26gt; 25% RR (red) + 50% Rr (pink) + 25% rr (white)
Reply:50% of the offspring are pink.





Parents: RR x WW


F1 = all RW pink


F2 = 1 red: 2 pink: 1 white


( 1 RR: 2 RW: 1 WW)
Reply:25%
Reply:75% of the F2 generation wil be pink.
Reply:25% will be pink in the F2 Generation.
