for the com bination of two recombinant gametes.

Each F2 genotype frequency must also be weighted to account for a genotype's relative abundance. Constructing a 4 x 4 Punnett square using the four possible F1 gametes that are shown in Fig. 9.15 reveals that in the F2 population all double homozygote genotypes (e.g. —101) have a frequency of


1/i6, all 0 locus heterozygotes (e.g.
