Question

how many types of phenotypes and genotypes will be formed in f2 generation in co dominance​

Answer 1

Answer:

n F2 generation the phenotype ratio matches the genotype ratio. Characteristics of Codominance: In this case, both the genes of an allelomorphic pair express themselves equally in the F1 generation. Both the alleles express equally. The expressed phenotype is the combination of two phenotypes of the two alleles

Answer 2

Co-dominance

Explanation:

• If we try to define Co-dominance, it is simply the relationship where alleles lack dominant and recessive relationships and both result in same degree of phenotype character.
• This results in heterogeneous genotype to have a different phenotype from homozygous genotypes. Eventually leads to the same genotype and phenotype ratio.
• Now, if we see the generation of co-dominants in f2 generation, it will have

1. phenotypic ratio - 1 : 2 : 1
2. Genotypic ratio - 1 : 2 : 1

• Now, a cross is shown in the given picture (attached below) to show how these ratio come from.
