Explain the role of gene flow in the biological species concept.

Expert Solution & Answer

Summary Introduction

To review: The importance of gene flow with respect to the biological species concept.

Introduction:

According to the “Biological species concept”, a group of individuals with interbreeding members to produce a viable offspring is called “species”. “Gene flow” occurs by the transfer of alleles between individuals of a species, and this exchange of alleles tends to hold the individuals together genetically. Human beings are one of the best examples of the “biological species concept”.

Explanation of Solution

In the “biological species concept”, the members of a species become reproductively isolated through prezygotic and postzygotic barriers and thus produce a fertile offspring. These members do not breed with the members of other species. As the interruption of the gene flow is must for the production of a new species, but here the members of different species are not interbreeding; therefore, the gene flow is completely masked between different populations. Hence, in the “biological species concept”, there is a complete absence of gene flow.

What are biofertilizers and mention the significance

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
