Q. Assertion: Repetitive sequences and SNPs are found in various locations in human genome. Reason: Single base DNA differences help to trace human history.
A) Both assertion and reason are true and reason is the correct explanation of assertion.
B) Both assertion and reason are true but reason is not correct explanation of assertion.
C) Assertion is true, but reason is false.
D) Both assertion and reason are false.
Explanation
Repetitive sequences are repeated hundred or thousand times while single nucleotide polymorphism (SNPs) is found in about 1.4 million locations in human genome. Both repetitive sequences and SNPs are helpful in tracing human history and evolution
