Question

in case of dihybrid cross if one character show complete dominance and other character show incomplete dominance then calculate the ratio

Answer 1

in a dihybrid cross the phenotypic ratio will be
9:3:3:1

Answer 2

Explanation:

• In the case of dominance the ratio of the genotype is 1:2:1 and for the incomplete dominance the ratio will be the 1:2:1.

• If we take the pea seed with round and yellow coloured to cross with the  pea seed with wrinkle and green coloured then the genotypic ratio of the plant seed will be found as that 1:2:1:2:4:2:1:2:1 from the cases of dominance and the incomplete dominance.

• So, the ratio will be in the F1 generation is 1:1:1:1:2:2:2:2:4 .
