Which of the following is an example of a homozygous recessive genotype?

• RR

• Rr

• rr

• None of the above

Assuming that both parent plants in the diagram above are homozygous, why would all of the f1 generation have yellow phenotypes?

• because the f1 genotypes are homozygous

• because yellow is dominant over green

• because both parents passed on yellow alleles
