Detailed explanation-1: -Sexual reproduction results in genetic variation, or genetic differences, between parents and offspring. Offspring inherit one set of chromosomes from each parent. So, an offspring has a mixture of chromosomes (and alleles) from its two parents. Sexual reproduction also results in genetic variation among siblings.
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: -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-4: -Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly.
Detailed explanation-5: -Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
