PLease solve this giving the necessary explanation!!
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 for the two parents for all
possible matings producing the following offspring:

(a) 318 one-pod normal, 98 one-pod wrinkled.
(b) 323 three-pod normal, 106 three-pod wrinkled.
(c) 401 one-pod normal.
(d) 150 one-pod normal, 147 one-pod wrinkled,

I think you're supposed to look at the ratios involved (e.g. in the first one, it's roughly 3:1) and then figure out what sort of cross could produce that.

This is a classic Mendellian dihybrid cross with a ratio of 9:3:3:1 of plants with all dominant traits:plants with one dominant trait:plants with the other dominant trait:plants with all recessive traits. 
You must therefore look at the ratio of the plants, there were 400 plants in the cross (approximately) so you must look for the one that fits with the ratio that applies to the above format.
