The Table Below Shows the Haplotypes Relative to a Small

The table below shows the haplotypes relative to a small region on chromosome 2 for 10 strains of laboratory mice.All strains are homozygous with respect to the region in question.
What SNP shows the highest genetic diversity?
$$\begin{array} { | l | l | l | l | l | l | l | } \hline \text { Strain } & \text { SNP1 } & \text { SNP2 } & \text { SNPI } & \text { SNP4 } & \text { SNP5 } & \text { SNP6 } \\\hline 1 & \text { A } & \text { G } & \text { G } & \text { T } & \text { A } & \text { C } \\\hline 2 & \text { A } & \text { T } & \text { C } & \text { T } & \text { G } & \text { C } \\\hline 3 & \text { A } & \text { G } & \text { C } & \text { T } & \text { A } & \text { C } \\\hline 4 & \text { A } & \text { G } & \text { C } & \text { T } & \text { A } & \text { C } \\\hline5 & \text { T } & \text { G } & \text { C } & \text { G } & \text { A } & \text { C } \\\hline 6& \text { A } & \text { T } & \text { C } & \text { T } & \text { A } & \text { T } \\\hline 7 & \text { A } & \text { G } & \text { A } & \text { T } & \text { A } & \text { T } \\\hline8 & \text { T } & \text { G } & \text { C } & \text { G } & \text { G } & \text { C } \\\hline 9& \text { A } & \text { C } & \text { C } & \text { T } & \text { A } & \text { G } \\\hline 10& \text { A } & \text { G } & \text { T } & \text { A } & \text { A } & \text { G } \\\hline\end{array}$$
