A monohybrid cross was arranged where round organisms (genotype RR) were crossed to wrinkled organisms (genotype rr) with the R allele being dominant to the r allele. All the following are true except:
a. There are 2 different phenotypes in the F2.
b. 50% of individuals in the F2 are homozygous.
c. The recessive phenotype does not appear in the F1 individuals.
d. All individuals in the F1 generation carry the r allele.
e. All individuals in the F2 carry the r allele.
