Quizplus · Accepted Answer

Mutations are alterations in an organism's DNA, which can occur spontaneously or be caused by various factors such as radiation, chemicals, and errors during DNA replication. They can have various effects on the organism, ranging from no apparent effect to functional improvement to detrimental effects. Mutations can be passed on to the organism's offspring if they occur in germ cells (sperm or egg cells).
