BIOL 152 Chapter Notes - Chapter 22: Ring Species, Reproductive Isolation, Honda Fit
Document Summary
It is very difficult to apply because producing fertile offspring needs to be tested, and that requires resources and time not always readily available: because of this, the morphospecies concept is used more. In some cases, the effect can be extreme: as a general rule, the more closely related and therefore genetically similar a pair of species, the less extreme the genetic incompatibility between their genomes. Biol 152 chapter 22: speciation is a by-product of the genetic divergence of separate populations, speciation: the development of reproductive isolation between populations. It is a by-product of the genetic divergence of separated populations: it"s typically a gradual process. Tetraploid: polyploidy is when there are multiple chromosome sets, they may be allopolyploids, meaning that they are produced from hybridization of two different species. Biol 152 chapter 22: natural selection can enhance reproductive isolation, a third way natural selection is involved with speciation is through.
