Detailed explanation-1: -Sexual reproduction generates more variations than asexual reproduction. This happens because of contribution of DNA from two parents with their own variations which produces a novel combination in the offspring. Though asexual reproduction produces variations which are less in number.

Detailed explanation-2: -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-3: -For sexual reproduction, it requires two types of gametes i.e., male and female gametes. The fusion of male and female gametes is known as fertilisation and it is a compulsory event. The fusion of gametes results in the formation of a zygote.

Detailed explanation-4: -(i) It involves a single parent. (ii) It is slower than sexual reproduction. (iii) It produces progeny that are genetically identical with the parent but not with one another. (iv) The progeny of asexual reproduction can be termed as clones.

Detailed explanation-5: -Offsprings are identical to the parent genetically and morphologically. They are the exact copy or clone of the parent. There is no recombination of genetic material takes place in asexual reproduction. Hence, there is no variation or genetic variability seen in the individual produced by asexual reproduction.
