The answer is C. recessive

Explanation:

An organism's genotype is its specific combination of alleles for a given gene.

-Homozygous means that the organism has two copies of the same allele for a gene. An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene
