How many types of genotypes are formed in F2 generation of Dihybrid cross?

Hence 9 different genotypes are possible in Mendel dihybrid cross and the correct option is (B).

What are the four types of combinations formed in the F2 generation of Dihybrid cross?

This resulted in four different combinations of seeds in the F2 generation. They were wrinkled-yellow, round-yellow, wrinkled-green seeds and round-green in the phenotypic ratio of 9:3:3:1. During monohybrid cross of these traits, he observed the same pattern of dominance and inheritance.

What is the F2 generation?

Medical Definition of F2 generation



: the generation produced by interbreeding individuals of an F1 generation and consisting of individuals that exhibit the result of recombination and segregation of genes controlling traits for which stocks of the P1 generation differ. — called also second filial generation.

What two genes are inherited?

According to this law, the alleles of two pairs of trait separate independently of each other during gamete formation, and get randomly rearranged in the offspring at the time of fertilization, producing both parental and new combinations of traits.

What is dihybrid cross with example?

In a dihybrid cross, Mendel took a pair of contradicting traits together for crossing; for example color and the shape of seeds at a time. He picked the wrinkled-green seed and round-yellow seed and crossed them. He obtained only round-yellow seeds in the F1 generation.
