Solutions For An Introduction to Genetic Analysis Chapter 18 Problem 1P

In the three individuals tested above, we see that the individual 3 is heterozygous for three microsatellites. The three microsatellites are 1, 3, and 4. If we observe the individuals 1 and 2, the individual 1 has no heterozygous loci at all.

Similarly, the individual 2 is heterozygous for two microsatellites, while the individual 3 is heterozygous for 3 microsatellites.

Hence, the individual with the most heterozygous loci is individual 3 and the individual with the fewest number of heterozygous loci is individual 1.
