Quizplus · Accepted Answer

Spontaneous mutations are those that occur naturally and randomly, without being induced by any particular external agent. They can arise from errors in DNA replication, spontaneous chemical reactions, or other internal biological processes. In contrast, induced mutations are caused by known external agents such as radiation or certain chemicals, while nutritional mutations and chromosomal losses are specific types of genetic changes that can occur due to certain factors or conditions. Cosmic mutations are not a recognized term in the field of genetics.
