Question

Assertion :Species with low genetic variability are generally at greater risk of extinction than the species with more genetic variability. Reason: Species with low genetic variability are generally are more vulnerable to diseases, predators or other environmental challenges.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

• Genetic variability in species is defined as individuals differing in genotype, or the presence of genotypically different i.e either the presence of or the generation of, genetic differences.
• Species with low genetic variability are generally at greater risk of extinction than the species with more genetic variability because Species with low genetic variability are generally are more vulnerable to diseases, predators or other environmental challenges.
• Hence Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
• So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
