To calculate the coefficient of inbreeding for individual V-1, we need to trace the common ancestor between its parents. In this case, the common ancestor is individual III-2, who appears twice in the pedigree as the father of both II-2 and II-3.

To calculate the coefficient of inbreeding, we use the formula F = (1/2)n, where n is the number of common ancestors in the preceding generations. In this case, there is only one common ancestor (III-2) in the preceding generations, so n = 1.

Plugging this into the formula, we get F = (1/2)^1 = 1/2. However, we need to double this value because III-2 appears twice in the pedigree. So the final coefficient of inbreeding for individual V-1 is F = 2*(1/2)^1 = 1/2.

Simplifying further, we get F = 1/2^2 = 1/4. Therefore, the best choice for the coefficient of inbreeding for individual V-1 is C) 1/8.
