Chapter 13, Problem 1TQ

Summary Introduction

The formation of new and distinctive species during the course of evolution is termed as speciation. Speciation is the biological process in which a particular species splits to form more than a species. Speciation occurs due to genetic divergence.

Expert Solution & Answer

Answer to Problem 1TQ

In order to accomplish speciation, genetic divergence should be occurred when two populations are reproductively isolated.

Therefore, the option (b) is correct.

Explanation of Solution

Justify reasons for the correct statement:

Species can interbreed to produce offspring, but they cannot breed with other such groups; which indicates that they are reproductively isolated. Once, two populations of a species are isolated reproductively, genetic divergence must occur for speciation to happen. This is because, genetic divergence is the process in which the accumulation of independent genetic changes (DNA sequence of genes) of two or more populations of ancestral species for a long period of time, which leads to the formation of new species.

Option (b) is given as “genetic divergence”.

Hence, the option (b) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “gene flow”.

Gene flow is a process, in which passing of alleles occurs between dissimilar populations of the same species. But speciation occurs when populations of a species reproductively or geographically isolated. Hence, it is a wrong answer.

Option (c) is given as “coevolution”.

Coevolution is a process in which two or more species evolve together, so that they can adapt to their environments. Therefore, coevolution is not related to speciation. Hence, it is a wrong answer.

Option (d) is given as “convergent evolution”.

Convergent evolution is a process by which organisms evolve independently with similar traits. Therefore, convergent evolution is not related to speciation. Hence, it is a wrong answer.

Option (e) is given as “none of the above”.

The statement given in option (b) is needed for speciation to happen, once two populations are reproductively isolated. Hence, it is a wrong answer.

Hence, options (a), (c), (d), and (e) are incorrect.

Conclusion

Once two populations are reproductively isolated genetic divergence happens for the occurrence of speciation.
