C) Transposable elements
D) Regulatory sequences
E) Gene duplication

Question

Quizplus · Accepted Answer

The formation of gene families requires gene duplication, where a single gene is replicated and evolves independently. Over time, the duplicated genes accumulate mutations that may result in changes in their function, regulation, or expression patterns. These differences may lead to the emergence of novel protein functions, allowing for the diversification of a gene family. The other options (repetitive DNA, pseudogenes, transposable elements, and regulatory sequences) may play a role in genome organization and evolution, but they are not necessarily required for the formation of gene families.
