What is the F2 generation when the F1 generation of +++/y cv f is crossed with +++/Y? Can recombination be seen in the F2 generation? Solution Recombination seen in the F2 generation as +++/yY cv. Two parental types, carrying either the Y+ y+ allele combination seen in the original mother (the female of the P generation) or the Y y+ allele combination seen in the original father (the male of the P generation). The remaining half of the gametes will be of two recombinant types, in which reshuffling has produced either YY or Y y allele combinations not seen in the P generation parents of the F1 females..
