R is the allele for round seeds while r is the allele for wrinkled seeds Y is the allele for yellow seeds and y is the allele for green seedsIn a cross of paren class=

Respuesta :

We have two parents with RrYy genotype.

We can see the cross with a Punnett square, and look for the seeds with genotype RRyy or Rryy, which will produce round green seeds.

As we can see, 3/16 of the seeds will be round and green, which means C) 3/16 would be the right answer.
