| Description: @@® one type of gametes two types of gametes one type of gametes A In this two allele system, B specifies dark blue flowers; b, white. Plants that are homozygous (B or b) make one kind of gamete. Heterozygous plants (31;) have light blue flowers and make two kinds of gametes (B and b). p. q@ P.

This Punnett square shows that in each generation, the predicted proportion of offspring that will inherit two B alleles isp x p, or p2. Likewise, the proportion that will inherit both alleles is 2w, and the proportion that will inherit two b alleles is £12.
