What is the biological significance of sexual reproduction?

The main importance of sexual reproduction is to ensure selection at the level of individual genes. It is best to first talk about how asexual reproduction takes place. With any reproduction, mutations appear in the organism: positive, neutral and negative. Each clone inherits an entire genome from its only “parent”. If negative mutations are crossed out by individuals with positive mutations, then the good changes will be lost forever. If organisms reproduce sexually, then their descendants will combine the genomes of two individuals, and it may turn out that there will be fewer harmful mutations and more useful ones. This is the purpose of sexual reproduction – to preserve the good by removing the bad.
