WebApr 3, 2024 · They differ from monohybrid crosses in terms of number of traits, number of alleles, segregation pattern, and phenotypic ratio. By understanding the mechanisms behind dihybrid crosses and performing experiments such as Punnett squares, test crosses, and chi-square tests, we can gain insights into the genetic principles that govern inheritance ... WebThe F 1 hybrid plants were next self-fertilized (Aa×Aa) and this cross is known as a monohybrid cross. In the offspring of monohybrid crosses, or F 2 generation, Mendel repeatedly observed a phenotype ratio of three plants with the dominant phenotype to one plant with the recessive phenotype (3:1 phenotype ratio) in the F 2 generation.

A dihybrid cross tracks two traits. Both parents are heterozygous, and one allele for each trait exhibits complete dominance *. This means that both parents have recessive alleles, but exhibit the dominant phenotype. The phenotype ratio predicted for dihybrid cross is 9:3:3:1.

WebJan 17, 2024 · The F2 generation always produced a 3:1 ratio where the dominant trait is present three times as often as the recessive trait.
