In an epistatic pair of genes, what are the alleles being masked called?
AEpistatic alleles
BHemizygous alleles
CHypostatic alleles
DHomozygous alleles
Answer & Solution
Correct answer: C. Hypostatic alleles
1. Epistasis involves a masking gene and a masked gene.
2. The alleles doing the masking are the epistatic ones.
3. The alleles being masked or silenced are said to be hypostatic.
4. Often the biochemical basis is a pathway in which one gene's expression depends on another gene acting before it.
5. Hemizygous and homozygous describe how many alleles an individual carries, not which one masks the other.
