A group of scientists are studying the evolution of a particular trait in a population of animals. They find that the trait is influenced by multiple genes, each with a small effect. What is the most likely explanation for the evolution of this trait?
Q1. A group of scientists are studying the evolution of a particular trait in a population of animals. They find that the trait is influenced by multiple genes, each with a small effect. What is the most likely explanation for the evolution of this trait?
Answer: Polygenic inheritance with multiple genes contributing
Explanation: Polygenic inheritance explains small effect sizes, most tempting wrong option fails as single mutation is rare.
