In dihybrid cross the phenotypic ratio for the f1 generation is 1:1:1:1 and the the f2 phenotypic ratio is 9:3:3:1.
Phenotypic ratio refers to observable characteristics of an individual, such as height, eye color, and blood type. A person's phenotype is determined by both genomic organization (genotype) and environmental factors.
A dihybrid represents a mating experiment between two organisms in which the two traits are the exact same hybrid. Hybrid organisms are heterozygous, meaning they have two different alleles at a particular genetic position or locus.
The main difference between the F1 and F2 generations is that the F1 generation is the first daughter generation of the parent's descendants. However, the F2 generation is the second daughter generation of the inbred progeny of the F1 individuals.
