Detailed explanation-1: -Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes. Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live.

Detailed explanation-2: -Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.

Detailed explanation-3: -Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).

Detailed explanation-4: -In asexual reproduction an exact genetic copy of the parent organism is produced (a clone ). Unlike sexual reproduction, asexual reproduction only introduces genetic variation into the population if a random mutation in the organism’s DNA is passed on to the offspring.

Detailed explanation-5: -Asexual species, on the other hand, do not have genetic variability like we do-each of their offspring has the exact same genetic makeup as their parent.
