Detailed explanation-1: -Not all living organisms reproduce sexually, there are some living organisms, which also reproduce asexually. Sexual reproduction takes place in humans, animals, insects, birds, higher plants, and reptiles.

Detailed explanation-2: -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-3: -Some organisms are able to do both sexual and asexual reproduction. This is particularly true for fungi and plants (and rarely, animals-as in parthenogenesis). Often, the type of reproduction that they undergo depends on their environmental conditions or the point in their growth cycles.

Detailed explanation-4: -The majority of animal species reproduce sexually. Sexual reproduction is generally considered to be advantageous because it results in genetically variable progeny due to segregation and recombination events (Williams, 1975; Maynard Smith, 1978; Bell, 1982).
