A chromosome have two genes X and Y. Gene Y influences the phenotypic effect of gene X.Based on the influential phenotypic effect, the gene Y is:
Correct answer: B. Epistatic to gene X.
- A. Linked to gene X
- B. Epistatic to gene X.
- C. Hypostatic to gene X.
- D. Independent of gene X for its expression
Explanation
The correct answer is epistatic to gene X. Epistasis is a genetic interaction where the phenotype of one gene (gene Y) affects or masks the expression of another gene (gene X). This is different from linked genes, which are simply located near each other on the chromosome and do not necessarily influence each other's phenotypic expression. Hypostatic refers to the gene that is being masked (in this case, gene X), and independence would mean gene Y does not affect gene X at all, which is not the scenario described.
