Question

Genes which influence the other gene to have effect on the same character are

• A. Epistasis genes
• B. Holandric genes
• C. Operator genes
• D. Antiepistasis genes

Answer 1

The correct option is A Epistasis genes

There are multiple alleles of the same gene which cause the effect on the same character. For example, there are different alleles of the same gene present in the humans which control the hypertension phenomenon. There are gene interactions which are an additive type or non-additive type. Epistasis is a non-additive type of interaction in the genes. When the genes act on the character, they cause different effects. But when there is interaction between the two alleles of the gene, there is synergistic effect produced on the character. One of the gene influences the other gene in a different way and the result can be observed in the phenotype of the organism.

Thus, the correct answer is option A.
