Question

1. suppose that frogs can have either high blood pressure or low blood pressure, and this is controlled by bands 10 - 12. the dna scan shown below is from a frog that has low blood pressure. which dna scan below was also obtained from a frog with low blood pressure? (options a, b, c, d with corresponding dna scans as shown in the image)

Explanation:

The reference low blood pressure frog's DNA scan has bands at positions 10-12. We match this pattern to the options:

• Scan A has bands at 10-12, matching the reference.
• Scan B has a band only at 10, not matching.
• Scan C has bands outside 10-12, not matching.
• Scan D has bands outside 10-12, not matching.

Answer:

A. DNA scan with bands at positions 10-12
