ehidna [41]

Answer:

AA, Aa and aa  genotypes will be produced.

Explanation:

If two birds with AA and aa genotypes are crossed, 4 offspring with Aa phenotype may be produced in F1 generation.

P generation:                      AA   x aa

                                           /   \        /  \

F1 generation:                Aa  Aa  Aa  Aa

When these F1 generation birds will be allowed to breed, the genotype of the F2 offspring will be as under:

                                    Aa    x  Aa

                                    /   \        /  \

F2 generation:       AA   Aa  Aa  aa

3 types of genotypes AA, Aa and aa will be produced in F2 generation. Their ratio will be AA : Aa : aa = 1 : 2 : 1.
