Document Summary
Mule, where the x and y could be incompatible (hetero zygo. Postzygotic isolation - after the zygote forms some thing happens to the zygote. Prezygotic isolation - mate choice (reinforcement) chooses to mate and breed. Divergence in sexual selection could be a separation of population, mutation, etc. Prezygotic isolation occurs before postzygotic isolation, could lead to incompatible mating signals, limits the gene flow even they though can breed with each other. Greenish warblers a ring species that have adapted to lower altitudes but still very cold, as they spread around the tibetan plateau; resulting in southern and northern populations. They don"t breed most likely due to songs that they use to mate, females with not accept songs from the other sub-species. Speciosity, when one population is driven to divide in to many sub-species.
