1. Advantages of sexual reproduction: it can produce genetic variation and is conducive to biological evolution.

2. Disadvantages of sexual reproduction: reproductive speed is not conducive to maintaining maternal Excellence.

Advantages of asexual reproduction: the number of offspring produced is large, the speed is fast, and the variation is small, which is conducive to maintaining the excellent characteristics of the mother? .

4. Disadvantages of asexual reproduction: poor adaptability, and long-term asexual reproduction will cause variety degradation.

Sexual reproduction refers to the reproductive mode in which sexual germ cells (gametes) produced by parents combine with bisexual germ cells (such as sperm and egg cells) to become fertilized eggs, and then the fertilized eggs develop into new individuals, which is called sexual reproduction.

Asexual reproduction is a reproductive mode that directly produces new individuals from the mother without the combination of bisexual reproductive cells. It can be divided into fission propagation (bacteria and protozoa) and budding propagation (yeast, hydra, etc.). ), spore propagation (ferns, etc. ) and vegetative propagation (strawberry stolons, etc. ), can shorten the plant growth cycle and retain the excellent characteristics of the female parent.

Life phenomena, such as hydra budding and unintentional willow insertion, are actually asexual reproduction.

Extended data:

The wide variation of gene combination in sexual reproduction can increase the ability of offspring to adapt to natural selection. The random combination of genes in the offspring produced by sexual reproduction may be beneficial or unfavorable to the species, but at least it will increase the chances of a few individuals living in an unpredictable and changing environment, thus benefiting the species.

Sexual reproduction can also promote the spread of favorable mutations in the population. If two individuals in a species have favorable mutations at different sites, in an asexual population, the two mutations will compete until one is eliminated, and it is impossible to maintain two favorable mutations at the same time.

In a sexually reproductive population, through mating and recombination, these two favorable mutations can enter the genome of the same individual and spread in the population at the same time.
