Detailed explanation-1: -Eukaryotes can reproduce both asexually through mitosis and sexually through meiosis and gamete fusion. In mitosis, one cell divides to produce two genetically identical cells. In meiosis, DNA replication is followed by two rounds of cell division to produce four haploid daughter cells that act as sex cells or gametes.

Detailed explanation-2: -All Eukaryotes Are Sexual, unless Proven Otherwise: Many So-Called Asexuals Present Meiotic Machinery and Might Be Able to Have Sex.

Detailed explanation-3: -Two modes of sexual reproduction exist in eukaryotic microbes: meiotic sex and parasexual cycles [1]. Meiotic sex is the reduction of a diploid cell to a haploid state and the eventual unification of two haploid cells to create a diploid zygote.

Detailed explanation-4: -Almost all eukaryotes reproduce sexually at some stage of their life cycle, and many are obligate sexual reproducers. Only about 1 percent of plants and 0.1 percent of animal species reproduce asexually, i.e. by making genetic clones of themselves (Otto, 2009).

Detailed explanation-5: -Protists, plants, fungi, and even animals can reproduce without sex. This asexual reproduction simply involves making a duplicate cell of the existing organism that develops into a new individual. Asexual reproduction in unicellular organisms simply involves a cell splitting in half.
