Two non-allelic genes produces the new phenotype when present together but fail to do so independently then it is called:
Correct answer: A. Epistasis
- A. Epistasis
- B. Polygene
- C. Non-complementary gene
- D. Complementary gene
Explanation
The correct term for the described scenario where two nonallelic genes produce a new phenotype when present together but fail to do so independently is "a. Epistasis." Epistasis involves genetic interactions in which one gene masks or modifies the effects of another gene, resulting in novel or modified phenotypes when specific gene combinations are present

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.

A gene is said to be dominant if:
There are three genes a, b, c. The percentage of crossing over between a and b is 20%, b and c is 28% and a and c is 8%. What is the sequence of genes on the chromosome?
