Well done
Yh correct but one ques missing how do variations occur s?
Hhehehe..
So tell the ans also
he variation occurs both within and among populations, supported by individual carriers of the variant genes. Genetic variation is brought about, fundamentally, by mutation, which is a permanent change in the chemical structure of chromosomes. Genetic recombination also produces changes within alleles.
