If an organism is homozygous recessive for a trait, which description fits its genotype?

Explanation:
Homozygous recessive means an organism carries two recessive alleles for a gene. So the genotype is two recessive alleles, one on each chromosome. This differs from having two dominant alleles (homozygous dominant) or having one dominant and one recessive (heterozygous). Saying there are two different alleles could imply heterozygous, but it doesn’t specify that both are recessive.
