Which of the following is a reason that a somatic (body) cell mutation might be found in cells close to the original source of the mutation? A somatic mutation would stay close to the germ cells.

The somatic mutation left the nucleus and infected neighboring cells.

The original mutant cell or cells underwent cell division and produced new cells carrying the mutation.

The mutation leaked away from the original source into surrounding cells.

the answer is d hope this

the right option is; decreased genetic variation  

decreased genetic variation describes the effect of this environmental change.

genetic variation is the naturally occurring genetic diversities or differences between organisms of the same species in a population. genetic variation allows the survival and adaptability of a species when they encounter changing environmental conditions. when an endangered species reduces, it loses genetic variation which may not be restored even if the species rebound and will only be recovered through the gradual collection of mutations over many years.
