Origin of Species
... • The resulting offspring having one copy of the chromosomes of the species is usually infertile because the chromosome do not pair correctly in meiosis. However such individuals are often otherwise healthy, can reproduce asexually, and can even become fertile through a variety of events. For exampl ...

Testing for Natural Selection on Conserved Non-genic Sequences in Mammals
... The observation of high DNA sequence conservation across long periods of evolutionary time is thought to be a good signal of important regions. Otherwise, the similarity between sequences of species would have eroded by neutral mutation processes. This is also why, in general, higher conservation is ...
