While … In reproductive biology, a hermaphrodite is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicates, pulmo…

WitrynaNematode hermaphrodites may reproduce either by self-fertilization or by crossing with males. When hermaphrodites cross with males, the male sperm are able to outcompete the sperm of hermaphrodites. The genetic basis for evolutionary transitions between dioecy and other kinds of reproduction were until recently unknown. define wavingThe gonad most likely to function is the ovary. The ovotestes show evidence of ovulation in 50% of cases. Spermatogenesis has only been observed in solitary testes and not in the testicular portions of ovotestes. According to a 1994 study, spermatogenesis has only been proven in two cases. One of the two cases, having XX,46/XY,46 mixture had fathered a child.
