Given below are two statements related to sympatric speciation:...
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 the most appropriate answer from the options given below.
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 the most appropriate answer from the options given below.
Options
- ABoth Statement (I) and Statement (II) are correct.
- BBoth Statement (I) and Statement (II) are incorrect.
- CStatement (I) is correct but Statement (II) is incorrect.
- DStatement (I) is incorrect but Statement (II) is correct.
Correct answer
C. Statement (I) is correct but Statement (II) is incorrect.
Step-by-step 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.
