What is the biological species concept quizlet?

What is the biological species concept quizlet?

biological species concept. states that a species is a group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring; they do not breed successfully with other populations. microevolution. changes over time in allele frequencies in a population.

Which is true about the biological species concept?

The biological species concept defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance. Although appearance is helpful in identifying species, it does not define species. Organisms may look different and yet be the same species.

How do reproductive barriers relate to the biological species concept quizlet?

How do reproductive barriers relate to the biological species concept? Reproductive barriers prevent two populations from interbreeding, producing unique species. Both prezygotic and postzygotic reproductive barriers prevent interbreeding among populations, leading to species divergence.

What is a potential problem with the PSC phylogenetic species concept?

What is a potential problem with the PSC (phylogenetic species concept)? It fails to recognize many monophyletic species. It leads to the recognition of a much smaller number of species than the biological species concept. It cannot be applied to organisms that reproduce asexually.

Does the phylogenetic species concept accommodates asexual reproduction?

This concept accommodates asexual and sexual species. The phylogenetic species concept defines a species as a set of organisms with a unique genetic history.

Why are species concepts important?

Species are important because they represent an important level of integration in living nature. This recognition is fun- damental to pure biology, no less than to all subdivisions of applied biol- ogy. An inventory of the species of animals and plants of the world is the base line of further research in biology.
