Web2. okt 2024 · The key difference between phenotype and genotype ratio is that the phenotype ratio is the relative number of or the pattern of the offspring manifesting t. ... The pattern of the physical expressions of the offspring for a trait is we call phenotypic ratio. Consider the following example d=shown in figure 01. The phenotypic ratio is 9:3:3:1. WebTypical dihybrid Mendelian pheno-typic ratios are 9:3:3:1 for AaBb X Aabb crosses. If the genes involved interact in their effects on the pheno-type, altered phenotypic ratios such as 9:3:4, 9:7, 12:3:1 and others may result as a consequence of gene interactions called epistasis. The colors of onions found in grocery stores are a relevant example.
