Question

Quizplus · Accepted Answer

A defect in a single gene is known as a mutation. A mutation is a permanent change in the DNA sequence that makes up a gene, and it may disrupt the gene's normal function. Carriers carry one copy of a mutated gene but do not show symptoms of the condition. An allele is a variant form of a gene, and a link refers to a relationship between two or more things.
