Detailed explanation-1: -Single celled organisms such as bacteria reproduce asexually. Among complex organisms, many plants and even some animals do too. These include bananas, starfish, and even komodo dragons. Despite this, up to 99% of complex organisms reproduce sexually, at least some of the time.

Detailed explanation-2: -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).

Detailed explanation-3: -All sexually reproducing species have certain key life cycle features in common, such as meiosis (the production of haploid cells from diploid ones) and fertilization (the fusion of haploid gametes to form a diploid cell called the zygote).
