In NOVAs Evolution Lab, students will explore the evidence of evolution through the lens of phylogeny. Consider the two owls; in the north, the climate is cooler than in the south; the other types of organisms in each ecosystem differ, as do their behaviors and habits; also, the hunting habits and prey choices of the owls in the south vary from the northern ones.

The cultivated forms of wheat, cotton, and tobacco plants are all allopolyploids. Through the evolutionary process of speciationwhich begins when populations become isolated by changes in geography or by shifts in behavior so that they no longer interbreed. For example, if a plant species with 2n = 6 produces autopolyploid gametes that are also diploid (2n = 6, when they should be n = 3), the gametes now have twice as many chromosomes as they should have.

Although polyploidy occurs occasionally in animals, most chromosomal abnormalities in animals are lethal; it takes place most commonly in plants. Speciation. registered in England (Company No 02017289) with its registered office at Building 3, Postzygotic mechanisms include genetic incompatibilities that prevent proper development of the offspring, or if the offspring live, they may be unable to produce viable gametes themselves as in the example of the mule, the infertile offspring of a female horse and a male donkey.
