Detailed explanation-1: -Sexual reproduction results in genetic variation, or genetic differences, between parents and offspring.
Detailed explanation-2: -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-3: -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-4: -The three main sources of genetic variation arising from sexual reproduction are: Crossing over (in prophase I) Random assortment of chromosomes (in metaphase I) Random fusion of gametes from different parents.
