The correct answer is:
B. They are homozygous.
Homozygous organisms have two identical alleles for a particular trait, while heterozygous organisms have two different alleles. Hybrid is a term that often refers to heterozygous organisms. Dominance refers to the relationship between alleles, not the genetic makeup itself.
