Phenotype in dihybrid cross

WebJan 24, 2024 · Monohybrid Cross: F2 generation . Should the F 1 generation be allowed to self-pollinate, the potential allele combinations will be different in the next generation (F 2 generation). The F 2 generation would have genotypes of (GG, Gg, and gg) and a genotypic ratio of 1:2:1. One-fourth of the F 2 generation would be homozygous dominant (GG), one … WebA dihybrid cross is a cross between individuals that involves two pairs of contrasting traits. Predicting the results of a dihybrid cross is more complicated than predicting the results of a monohybrid cross. All possible combinations of the four alleles from each parent must be considered. We will examine a dihybrid cross involving both color ...
