Which type of mutation cannot occur in a child after birth? germline mutation somatic mutation point mutation frameshift mutation

The correct answer would be germline mutations.

Gemline mutations are the mutations that only take place in the germ cells of an individual. These mutations are passed on to the offspring when mutated egg or sperm is involved in fertilization.

The offspring developed from the mutated germ cells will carry the mutation in every somatic cell of the body.

These mutations can occur during any stage of zygote development or before the fertilization.

After birth, mutation usually occurs in somatic cell (somatic mutation). It can be caused by various physical or chemical factors such as ultraviolet rays, carcinogens et cetera. It can be of various types such as point mutation, frameshift mutation et cetera.
