• B. dominance
• C. mutation
• D. epistasis

Answer 1

The correct option is D

epistasis

The correct option is D:

Explanation of correct option

Epistasis is the phenomenon where a gene pair hides the effect of another gene that is non-allelic.

Explanation of incorrect option

Option A

Segregation refers to the separation of gene variants into cells.

Option B

1. Dominance is where one allele of a particular trait is expressed in a heterozygous individual.
2. In the gene determining height, the tall allele masks the short allele.

Option C

1. A mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations.
2. This is caused by the alteration of single base units in DNA or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes

Final answer

A gene pair hides the effect of another gene the phenomenon is called epistasis.
