Question

which type of reproduction, asexual or sexual, results in offspring with greater genetic variation?

Answer 1

sexual reproduction results in greater genetic variation in the offspring due to phenomenon of recombination, crossing over during meiosis .

parental characters are exchanged and new characters are acquired.
the organism builds up its own new DNA thus resulting in greater genetic variation.

THE SIMPLEST EXAMPLE BEING HUMAN BEINS, VARIOUS SPECIES OF PLANTS AND ANIMALS.

lack of genetic variation would have resulted in clones as it does in asexual reproduction in most cases.
