Biology - Evolution Question with Solution | TestHub
Given below are two statements related to sympatric speciation:
Statement (I): Formation of species within single population without geographical isolation is sympatric speciation.
Statement (II): Migration of individuals is helpful in sympatric speciation.
In light of the above statements, choose themost appropriateanswer from the options given below.
Options:
Answer:
Solution:
Sympatric speciation is the process through which new species evolve from a single ancestral species while inhabiting the same geographic region. It occurs without any geographical isolation, making Statement (I) correct.
Migration of individuals leads to gene flow between populations or subpopulations, which tends to homogenize the gene pool and prevent the reproductive isolation necessary for speciation. Therefore, migration is a barrier to sympatric speciation rather than being helpful, making Statement (II) incorrect.
Answer: Statement (I) is correct but Statement (II) is incorrect.
