Answer:

D

Step-by-step explanation:

A recessive trait is usually the phenotype of the gene allele that is masked by the other dominant allele of the same gene loci. Therefore, for its phenotype fo be exhibited in the individual, it has to occur in the homozygous state in the genotype. Usually, the recessive gene is associated with a malfunctioning gene hence causes disorder in the homozygous state.
