Question
It occurs when a single gene has more than one phenotypic expression.
Group of answer choices
- multifactorial
- codominance
- epistasis
- polygenic
- pleiotropy
Solution
The correct answer is pleiotropy.
Explanation:
Pleiotropy refers to the phenomenon where a single gene influences multiple phenotypic traits. This means that a single gene can have effects on various aspects of an organism's phenotype, leading to diverse characteristics being expressed as a result of changes in that one gene. This is in contrast to concepts like polygenic inheritance, where multiple genes contribute to a single trait, or epistasis, where the expression of one gene is influenced by another gene.
In multifactorial inheritance, traits are influenced by multiple genes and environmental factors. Codominance refers to a situation where two different alleles are expressed equally in the phenotype. Therefore, in this context, pleiotropy is the most appropriate choice.
