Question

Quizplus · Accepted Answer

Genetic mutations are changes in the DNA sequence that can result in alterations in the structure, function, or regulation of proteins. The majority of these mutations are deleterious, as they can disrupt gene expression, alter protein function, or result in diseases. While some mutations can provide a selective advantage to an individual, they are rare and often come with a trade-off, such as increased susceptibility to other diseases. Therefore, it is incorrect to state that genetic mutations have mostly beneficial effects or always confer selective advantages to the offspring.
