WebThe Dobzhansky–Muller incompatibilities can result from purely random, neutral or non-selected differences between the populations. They can also be driven by natural selection in at least two ways. When two populations diverge from each other and encounter new - and different - environments they may adapt to these environments. WebThe extent and nature of genetic incompatibilities between incipient races and sibling species is of fundamental importance to our view of speciation. However, with the exception of hybrid inviability and sterility factors, little is known about the extent of other, more subtle genetic incompatibilities between incipient species.
