A gene pair hides the effect of another gene. The phenomenon is called:
Correct answer: C. Epistasis
- A. Dominance
- B. Segregation
- C. Epistasis
- D. Mutation
Explanation
Epistasis is the phenomenon where a gene at one locus (epistatic gene) can hide or modify the effects of a gene at another locus (hypostatic gene) on a specific trait or phenotype. It is a form of genetic interaction and differs from dominance, segregation, and mutations, which have their own specific roles in genetics.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
