Male mice grow ovaries instead of testes if they are missing a small region of DNA that doesn't contain any genes, finds a new paper published in Science.
The study, led by researchers at the Francis Crick Institute, could help explain disorders of sex development in humans, at least half of which have an unknown genetic cause.
Mammals will develop ovaries and become females unless the early sex organs have enough of a protein called SOX9 at a key stage in their development. SOX9 causes these organs to become testes, which then direct the rest of the embryo to become male.

The use of ortho and hetero, see orthodoxy, orthography, predates the hetero/homo use.
My argument is that hetero/homo avoids making a judgment on normality, which ortho/hetero would have done, but reverses the connotation of hetero. Not the most straightforward way to express oneself.
On one hand the science is not about judgement, on the other hand it's not a moral judgement and in other cases science makes use of the added connotation, see orthodontics.
