Deformities and Hermaphroditism in Crustaceans

Hermaphroditism

Crustaceans

between species, but between different segments on the same animal. They have limbs specially adapted for walking, eating, grooming, swimming, mating, sensing the surrounding environment, brooding young, spearing prey, scraping surfaces and even snapping to make noise. Lobsters provide a good example of the limb diversity that can exist on even a single individual — the thoracic and abdominal a...

Sex and hermaphroditism in the Penna model

I compared sexual(SX) and hermaphroditic(HA) reproduction schemes within the Penna model[1]. A fixed set of parameters was used, to make the results comparable with recent simulations[2]. I also reproduced the results for a selfemerging dominance[2] in an independant simulation for both hermaphroditic and sexual cases. A variation on partner selection was also implemented, this shifted stable p...

Child with True Hermaphroditism

True hermaphrodites possess both ovarian and testicular tissues which may be present in separate gonads or combined in an ovotestis. External and internal genitalia are ambiguous and variable, though a prominent penial structure is usual. Chromosome examination of true hermaphroditism has revealed an XX sex chromosome complement in the majority of cases, but the XY complement and different mosa...
