What is the evolutionary basis for sexual selection sex bene

What is the evolutionary basis for sexual selection? (sex, beneficial genes, swap together, new combination, increase social bonding)

Solution

Sexual selection is the ability of the organism to copulate with a specific species.Sexual selection is a type of natural selection.
It is considered as natural selection because one biological species always prefer opposite sexual species for mating and compete with the same species group.
Genetic variation, difference in sexual reproduction, mutations, change in the characteristics of hereditary and migration may lead to evolution.
Mutations are the sudden changes that occur in the nucleotide sequence of the genome of DNA.
Due to these type of alterations they may be a variation in the genes that are formed as new combination.
Mutations may also seen in some migrated species and this genetic variation may cause variation in sexual reproduction.
This genetic variation leads to gene flow that is the genes are moved from one population to another population.
Now the genetic variation may lead to the difference in the characteristics of the hereditary of the organisms.
These factors are the basis of the evolutionary process and it also leads to the natural selection. Natural selection is the basic mechanism of evolution.
Thus all the above characters describe the evolutionary basis of sexual selection.
