Quizplus · Accepted Answer

Pleiotropy refers to the phenomenon where a single gene can have multiple effects on an organism's phenotype. This can include effects on traits that are seemingly unrelated, due to the gene's influence on various biochemical pathways. Examples include the sickle cell gene, which affects not only red blood cell shape but also susceptibility to certain diseases, and the PKU gene, which affects not only metabolism of phenylalanine but also neurological development.
