Describe the process of speciation. include in your discussion the factors that may contribute to the maintenance of genetic isolation.

The process of speciation is the separation of a specific population into different species. The factors that may affect to maintain this genetic isolation are: allopatric, sympatric, prezygotic and postzygotic barriers. Allopatric barriers occurs when two species that are of the same family before cannot go back to the way they were before unless a contact between the two is established again. Sympatric are a group of species that shared the same family before but forced to evolve separately due to environmental factors. Prezygotic barriers are a group of species that are formed from the developing fertilized egg.
