How sexul reproduction
in an organism
causes variationt​

Answer 1

Answer:

There is an exchange of genetic material between homologous chromosomes during formation of gametes. In case of asexual reproduction, variation is significantly less since only a single parent is involved. Very small changes occur due to inaccuracies during DNA copying that pass on to the progeny.

Answer 2

Answer:

The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. A disadvantage is that sexual reproduction takes longer than asexual reproduction.
