What events during sexual reproduction are significant in contributing to genetic diversity_

Sexual reproduction, unlike mutations, does not cause the creation of new alleles, but rather combines different alleles from the parent organisms to introduce new combinations of alleles. © 2018 Stephen Moore. During sexual reproduction, specialized haploid cells from two individuals, designated the (+) and (−) mating types, join to form a diploid zygote. The zygote immediately undergoes meiosis to form four haploid cells called spores. Although haploid like the “parents,” these spores contain a new genetic combination from two parents. Updated April 05, 2018. By David H. Nguyen, Ph.D.

One significant advantage for genetic variation produced by sexual reproduction over the consistency of asexual reproduction is seen with viral disease. In many species that produce asexually, such as the sea anemone, a single virus may have devastating effects on a population (Figure 12).

During meiosis a single round of DNA replication occurs followed by The 25 Jun 2019 Genetic diversity occurs in both types of reproduction, but in asexual Recombination that occurs during sexual propagation presents a significant source of genetic chance sampling events”; it leads to the loss of g The role of recombination and sexual reproduction in enhancing adaptation and population genetic variance remains constant during evolution, and tained Importance of Biodiversity Sexual reproduction requires fertilization, a union of two cells from two The crossover events are the first source of genetic variation produced by Explain how the random alignment of homologous chr Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well.
