A)Duplication
B)Deletion

E)Nonreciprocal translocation

Question

Quizplus · Accepted Answer

Multigene families arise from gene duplication events, where a single gene is duplicated and creates multiple copies of itself within the genome. Over time, these duplicated genes may accumulate mutations that lead to functional divergence, resulting in a family of related genes that perform different but related functions. Hemoglobin genes, for example, are part of a multigene family that has evolved through multiple rounds of gene duplication and divergence.
