WebTemporal isolation is a prezygotic barrier that leads to speciation, or the formation of new species. Other types of prezygotic barriers include geographic, reproductive, and behavioral isolation. When two populations of one species are isolated this way, they no longer reproduce with each other due to differences in mating times. WebGametic isolation happens when the egg and sperm are released but a zygote is not formed. A zygote is the cell produced when an egg and sperm unite. Another example of gametic isolation happens when the sperm is unable to survive or will be less mobile in the reproductive tract of a female from a different species.
