Answer

(e) heterozygote

Work Step by Step

Unlike a homozygote where both alleles are the same (RR or rr), a heterozygote has two alleles that are different. This can only be represented one way: Rr. There will be one dominant (R) allele and one recessive (r) allele in a heterozygote. This comes from the root hetero- which means different.
