Detailed explanation-1: -Nearly all animals employ a diploid-dominant life-cycle strategy in which the only haploid cells produced by the organism are the gametes. The gametes are produced from diploid germ cells, a special cell line that only produces gametes.

Detailed explanation-2: -In sexual reproduction, sex cells (gametes) from two parents combine in the process of fertilization, leading to the formation of a new, genetically distinct individual.

Detailed explanation-3: -Animals that reproduce asexually include planarians, many annelid worms including polychaetes and some oligochaetes, turbellarians and sea stars. Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemmae in liverworts.

Detailed explanation-4: -Asexual reproduction occurs in prokaryotic microorganisms (bacteria) and in some eukaryotic single-celled and multi-celled organisms.
