<span>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. </span>
