6.1: Dihybrid CrossesSOLVED: What does a phenotype ratio of 3:1 among offspring in a
monohybrid cross indicate?
The alleles that govern one trait assort into gametes together
with the alleles that govern another trait.
It indicates that the alleles governing the phenotypes ha3:1 Ratio - Biology As PoetryThe phenotypic ratio for Mendel’s dihybrid cross isIn both incomplete dominance and codominance, both phenotypic and genotypic ratios are identical 1:2:1 in F2 generation. In incomplete dominance, the phenotype of hybrid is intermediate between the two parents as both the alleles express themselves partially. However, in codominance, there is no intermediate expression as both the alleles express themselves equally. In incomplete dominance, the phenotypic effect of one allele is more prominent than the other while in codominance the phenotypic effect of both the alleles is equally prominent and therefore, they produce altogether a third type of phenotype.
