Abstract:

The generation and evolution of sexual reproduction is one of the most important and controversial issues in evolutionary biology. The inherent costs of sexual reproduction make it difficult to interpret its maintenance. In many hypotheses of Fisher's understanding of the current genome size in the early 20th century, host-parasite co-evolutionary theory (the Red Queen hypothesis) has received a lot of attention, and mathematical modeling and experimental support and controversies have accumulated. This theory mainly believes that stress from co-evolving parasites can be an important force in maintaining sexual reproduction in selection and sexual reproduction can create rare genotypes to fight parasitic infections with selective advantages. Compared with its intrinsic cost, it’s still helpful.
