Below is an alignment of a portion of the mtDNA genome from several humans and chimpanzees. The first human sequence is shown in full and the other sequences are compared to it. A dot indicates the place where the base pair of the sequence matches the first sequence (Human #1). The nucleotide is indicated where there is a mismatch when compared to the Human #1 sequence. A dash indicates a base pair is missing (a deletion) when compared to the Human #1 sequence.

Give the base pair number for a SNP marker that is fixed between human and chimps. IZ ‘ase pair b. Give the base pair number for a SNP marker that would be useful for studying population variation within humans. 4 base pair Give the base pair number for a SNP marker that would be useful for studying population variation within chimps.
