Asexual reproduction does not produce variety in population, unless through mutations, because offspring are exact copies of their parent – because they reproduce by binary fission.
Explanation:
Sexual reproduction produces variations by genetic combinations. Remember during meiosis, there is the crossing over of chromosomes. In addition during fertilization, in sexual reproduction, each gamete brings in alternative forms of alleles of genes. The advantage of asexual reproduction is that it allows for fast reproduction because only one parent is involved in the formation of offspring.
