When a single gene has multiple phenotypic effects, the phenomenon is called:
Correct answer: C. Pleiotropy
- A. Codominance
- B. Epistasis
- C. Pleiotropy
- D. Sex-linkage
Explanation
"PLEIOTROPY" refers to the phenomenon in which a single locus affects two or more apparently unrelated phenotypic traits and is often identified as a single mutation that affects two or more wild-type traits.

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.
