Question

what are the genotypes of the F1 parent plants? genotype of F1 parent plant 1 genotype of F1 parent plant 2Punnet square down below.

Answer 1

We have only one trait with two variations or alleles in this example, which the exercise represents as R or r.

As we can see in the Punnet square, the parent's genotypes are RR x rr, so the offspring would be a probability of 100 % Rr genotype.

Another thing we could appreciate here is that the phenotypes of the parents are different since R (in RR) gives a particular form in the characteristics of the organism, and r (in rr), another one different, but in the offspring, all will be the same observable characteristic gave by Rr genotype.
