Question

if total no of seeds in f2 generation is 320; then find out the no of seeds having both dominant character

Answer 1

9:3:3:1 is the  ratio of dominant dominant:dominant recessive:recessive dominant :recessive recessive

Therefore, 9/16 will be the composition of dominant dominant progeny in f2 generation.

9/16*320=9*20=180

So there will be 180 seeds with both dominant characters
