Answer to Question #100581 in Genetics for David Kachapin

Question

How many F2 phenotypes Will be produced from the parental cross AABBCC x AABBCC?( Prove your answer using the crosses)

Answer 1

As both parents possess identical gene alleles, F1 and F2 will include individuals of the same phenotype - AABBCC.

As both parents and F1 offspring produce gametes with the genotype ABC, two crosses can be shown as:

As a result, only one phenotype (AABBCC) will be present in F2.
