Answer:
Major causes of variation include mutations, gene flow, and sexual reproduction. DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population.

Answer:
the reason for the variations in biodiversity all over the world is that every animal cannot survive the same situation.
