Question

which statement describes recessive alleles?
any allele that can hide the presence of a different allele
two alleles that are expressed separately and equally
any allele whose presence can be masked by another allele
two alleles that blend to create an intermediate phenotype

Explanation:

In genetics, a recessive allele is one that is not expressed when a dominant allele is present. The dominant allele masks the presence of the recessive allele. For example, in pea plants, the allele for tallness (T) is dominant over the allele for shortness (t). A plant with the genotype Tt will be tall because the dominant T allele masks the recessive t allele. Option A describes a dominant allele. Option B describes codominance. Option D describes incomplete dominance.

Answer:

C. any allele whose presence can be masked by another allele
