Q$6.$ What pattern of relatedness would you infer among four individuals based only on the following sequences from the same place in their chromosomes?

D$1$: AAAATTTT

D$2$: AAACTTTT

D$3$: ACCCTTTT

D$4$: CCCCGGTT

D$1$ and D$2$ are most closely related. D$1/$D$2$ are in turn most closely related to D$3,$ and D$4$ is the least related to the others.

D$1$ and D$2$ are closely related. D$3$ and D$4$ are also closely related. D$1/$D$2$ are more distantly related to D$3/$D$4.$

D$1$ and D$3$ are most closely related. D$1/$D$3$ are in turn most closely related to D$2,$ and D$4$ is the least related to the others.

D$1$ and D$3$ are closely related. D$2$ and D$4$ are closely related. D$1/$D$3$ are more distantly related to D$2/$D$4$
