Another common cause of being intersex is the crossing over of the SRY from the Y chromosome to the X chromosome during meiosis.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).Arthropods are the phylum with the largest number of species.
Monoecy is especially common in conifers, but occurs in only about 7% of angiosperm species.
Hermaphrodite is also used to describe any person incompatible with the biological gender binary, but in medicine, it has recently been replaced by intersex.
When spotted hyenas were first discovered by explorers, they were thought to be hermaphrodites.
Early observations of spotted hyenas in the wild led researchers to believe that all spotted hyenas, male and female, were born with what appeared to be a penis.
This condition is seen in many common garden plants.
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.
The distribution of self-fertilization rates among animals is similar to that of plants, suggesting that similar processes are operating to direct the evolution of selfing in animals and plants.
which derives from Hermaphroditus ( Ἑρμαϕρόδιτος), the son of Hermes and Aphrodite in Greek mythology.
For instance, groupers are favoured fish for eating in many Asian countries and are often aquacultured.
Since the adults take several years to change from female to male, the broodstock are extremely valuable individuals.
Intersex is thought by some to be caused by unusual sex hormones; the unusual hormones may be caused by an atypical set of sex chromosomes.
