Question

In a dihybrid cross, when one pair of alleles show incomplete dominance, genotypic ratio comes to be?

Answer 1

Answer:

The genotypic ratio of a di-hybrid cross will always remain the same. Therefore, the ratio becomes, 1: 2: 1: 2: 4: 2: 1: 2: 1. When a gene has no dominant factors, the phenotype of a heterozygous dominant individual will be a blend of recessive and dominant traits. This is called as Incomplete dominance.
