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.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
