A phenomenon of gene interaction in which a gene interferes in the effect of another gene is called:

Explanation

The correct answer is epistasis. Epistasis is a genetic phenomenon where the effect of one gene (the epistatic gene) interferes with or masks the expression of another gene (the hypostatic gene). This interaction can lead to complex phenotypic traits that are not predicted by the individual gene effects alone.Other options explained:Pleiotropy involves a single gene affecting multiple traits, not the interaction between different genes.Overdominance describes a situation where the heterozygote has a phenotype outside the range of the homozygotes, without involving gene interaction.Co-dominance occurs when two alleles are equally expressed in a heterozygote, resulting in both traits being visible, and does not involve gene interaction.
