Question

What would be the phenotypic ratio in F
generation in a dihybrid cross if both the genes show lethality in homozygous dominant state -
(1) 2:2:2:2 (2)4:2:2:1
(3) 6:3:2:1 (4)9:3:3:1​

Answer 1

Answer:

This 9:3:3:1 phenotypic ratio is the classic Mendelian ratio for a dihybrid cross in which the alleles of two different genes assort
