Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants. [6] [7] Sexual reproduction also occurs in some unicellular eukaryotes. [2] [8] Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such as bacteria and archaea.
The sexual conflict hypothesis suggest that polyandry can occur due to sexual coercion [18] preventing females from obtaining any benefits. Sexual coercion has been seen in three different forms: forced copulation, sexual harassment, and intimidation. Forced copulation is seen in those males that cannot gain access to females for mating.

While animals which externally fertilize are able to release egg and sperm, usually into the water, not needing a specific partner to reproduce.
Extra-pair copulation in men has been explained as being partly due to parental investment. [7] Research has suggested that copulation poses more of a risk to future investment for women, as they have the potential of becoming pregnant, and consequently require a large parental investment of the gestation period, and then further rearing of the offspring.

It occurs when the organism's sex changes at some point in its life. [1] A sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life. [2] Sequential hermaphroditism occurs in many fish, gastropods, and plants. Species that can undergo these changes do so as a normal event within their ...
