Which of these options are examples of how gene interactions can lead to changes in expected phenotypic ratios? A) Polygenic inheritance B) Complementation tests C) Pleiotropy D) Epistasis
Understand the Problem
The question is asking for examples of gene interactions that can influence phenotypic ratios, which involves understanding various genetic concepts.
Answer
Polygenic inheritance and Epistasis
The correct examples of how gene interactions can lead to changes in expected phenotypic ratios are A) Polygenic inheritance and D) Epistasis.
Answer for screen readers
The correct examples of how gene interactions can lead to changes in expected phenotypic ratios are A) Polygenic inheritance and D) Epistasis.
More Information
Gene interactions like polygenic inheritance involve multiple genes affecting a single trait, which can lead to a blend of phenotypes and alter ratios seen in simple Mendelian inheritance. Epistasis occurs when one gene's expression masks that of another, modifying expected ratios.
Tips
A common mistake is to confuse pleiotropy, where one gene affects multiple traits, with polygenic inheritance, where multiple genes affect a single trait.
