Why does sexual reproduction result in more genetic variation in a species than asexual reproduction?

The correct answer will be crossing over (genetic recombination) in sexual reproduction.

Explanation:

Reproduction in organisms takes place by two ways- sexual and asexual.

Sexual reproduction involves the fusion of two gametes and is bi-parental while asexual reproduction is uni-parental so does not involve fusion of two gametes and produce "clones" which are exact copies of themselves.

The key feature which takes place in sexual reproduction is that gamete formed involve the genetic information from both parents so, offsprings inherit characters of both the parents and after fertilization exchange of genetic material between homologous chromosomes takes place through a process known as "crossing over" which takes place during prophase of meiosis I. This crossing over or genetic recombination results in formation of new combinations of alleles increasing genetic diversity.

Thus, crossing over (genetic recombination) in sexual reproduction is the correct answer.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.

the sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.
