WebExplanation: Mutations are caused by an alteration in the DNA sequence. If these mutations pass on to the progeny, then they are termed as gametic mutation and if … WebMutation occurring in the germ cells (sperm or ovum) has been termed germinal mutation. Such mutations are again divided into gametic when occur in the gametes and zygotic when occur in the zygote. iii. Spontaneous mutation: The naturally occurring mutations are the spontaneous mutations.
