sexual reproduction is more likely to increase the chance of genetic variation than is asexual reproduction

Detailed explanation-1: -Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique. In asexual reproduction, one parent copies itself to form a genetically identical offspring.
Detailed explanation-2: -What are the main differences between asexual reproduction and sexual reproduction? Asexual reproduction requires two parents and produces non-identical offspring, while sexual reproduction requires only one parent and produces identical offspring.
Detailed explanation-3: -Asexual reproduction and evolution 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-4: -Sexual reproduction is more likely to increase genetic variation than is asexual reproduction. Only asexual reproduction results from the union of a sperm and an egg. Cell division only occurs after sexual reproduction. Only offspring from asexual reproduction inherit traits from two parents.
