Quizplus · Accepted Answer

Mutations are changes in the DNA sequence that occur during gene replication. These changes can be caused by a variety of random errors, such as mistakes made during DNA replication or exposure to mutagenic agents like radiation or certain chemicals. While mutations can have a variety of effects on an organism, they can also contribute to genetic diversity and evolution through natural selection. Mutations do not directly result from brain development, neurotransmission, or natural selection - rather, they are a random occurrence that can affect an individual's fitness and reproductive success over time.
