A closer analogy to hermaphroditism in botany is the presence of separate male and female flowers on the same individual—such plants are called monoecious.
Monoecy is especially common in conifers, but occurs in only about 7% of angiosperm species.
Some humans were historically termed true hermaphrodites if their gonadal tissue contained both testicular and ovarian tissue, or pseudohermaphrodites if their external appearance (phenotype) differed from sex expected from internal gonads.
This language has fallen out of favor due to misconceptions and pejorative connotations associated with the terms, and also a shift to nomenclature based on genetics.
Sequential hermaphroditism is common in fish (particularly teleost fish) and many gastropods (such as the common slipper shell), and some flowering plants.
Sequential hermaphrodites can be divided into three broad categories: Dichogamy can have both conservation-related implications for humans, as mentioned above, as well as economic implications.
The SRY is then activated in only certain areas, causing development of testes in some areas by beginning a series of events starting with the upregulation of SOX9, and in other areas not being active (causing the growth of ovarian tissues).
Thus, testicular and ovarian tissues will both be present in the same individual.
Upon fertilization of the two ova by two sperm cells (one carrying an X chromosome and the other carrying a Y chromosome), the two fertilized ova are then fused together resulting in a person having dual genitalial, gonadal (ovotestes) and genetic sex.
Another common cause of being intersex is the crossing over of the SRY from the Y chromosome to the X chromosome during meiosis.For instance, groupers are favoured fish for eating in many Asian countries and are often aquacultured.
