... reproductive isolating mechanisms can evolve afterwards. Whether a geographic barrier leads to allopatric speciation or not depends on dispersal ability. A barrier may lead to speciation in some groups but not in others. For example, a river may be a barrier for a snake but not a bird. In the Origin ...

Screenings Test for Inherited Disease (STID)

The overall frequency of such recessive diseases is 1 %, which is higher than the frequency of Down syndroom. STID screens healthy couples for carrie ...
