What are sexual reproducing species

Mottled ducks Anas fulvigula lay their eggs in grass nests near to the ground, usually close by water. Though this nest looks quite full with nine eggs, a clutch of mottled duck eggs can contain as many as twelve or thirteen eggs. Organisms are genetically diverse because of sexual reproduction. Sexual reproduction begins with sperm and egg cells, which are produced through a process called meiosis. These cells are referred to as haploid because they contain half of the number of chromosomes as the parent. In sexual reproduction, a haploid sperm from the male parent fertilizes the haploid egg from the female parent to produce what is called a diploid zygote.

People typically employ several arguments in their efforts to explain the prevalence of sexual reproduction. One such argument is that organisms engage in sex because it is pleasurable.

4 Types of Reproduction

Sexual reproduction occurs when living organisms combine genetic information from two different types. The male gender produces a mobile gamete which travels to fuse with a stationary gamete that is produced by the female gender. Gametes are germ cells that are able to unit with germ cells from the opposite gender.

Sexual reproduction is a process of biological reproduction by which organisms create descendants that have a combination of genetic material contributed by two different gametes, usually from two different organisms. A gamete is a mature reproductive or sex cell. Sexual reproduction results in increasing genetic diversity, since the union of these gametes produces an organism that is not genetically identical to the parent s. Sexual reproduction is characterized by two processes: meiosis , involving the halving of the number of chromosomes to produce gametes; and fertilization, involving the fusion of two gametes and the restoration of the original number of chromosomes. During meiosis, the chromosomes of each pair usually cross over to achieve genetic recombination.
