# Problem: in sesame plants, the one-pod condition (P) is dominant to the three-pod condition (p), and normal leaf (L) is dominant to wrinkled leaf (l). Pod type and leaf type are inherited independently. Determine the genotypes as best as you can for the two parents for all possible matings producing the following offspring.a) 318 one-pod normal, 98 one-pod wrinkledb) 74 one-pod normal, 72 one-pod wrinkled, 76 three-pod normal, 72 three-pod wrinkled

a) This has a 3:1 ratio for one-pod normal to one-pod wrinkled.

Having no three-pod variant, this should mean that on of the parents should be homozygous dominant, regardless of the genotype of the other.

A 3:1 ratio of normal to wrinkled leaves could only mean that it is a heterozygous cross.

The two information lead us to conclusion that there are three possible matings for this outcome:
