Which of the following statements correctly describes a multigene family?
A)It is composed of multiple genes whose products must be coordinately expressed.
B)It is made up of genes whose sequences are very similar and that probably arose by duplication.
C)It contains many tandem repeats such as those found in centromeres and telomeres.
D)It consists of a gene whose exons can be spliced in a number of different ways.

Question

Quizplus · Accepted Answer

A multigene family is a group of genes that have similar or identical DNA sequences, often because they have arisen by gene duplication. This can result in different copies of the gene taking on different functions or being expressed at different times or in different tissues. Therefore, option B correctly describes this type of gene family.
