Shared allele distance (Chakraborty and Jin, 1993) [Jin, L. 93]

between individuals:

\( D_{SA_{I}}=1-P_{SA_{I}} \), with \( P_{SA_{I}}=\frac{\sum ^{r}_{j}S}{2r} \)

where the number of shared alleles S is sumed over all loci r.

between populations:


\begin{displaymath}
D_{SA_{B}}=1-\frac{2\overline{P}_{SA_{B}}}{\overline{P}_{SA_{X}}+\overline{P}_{SA_{Y}}}\end{displaymath}

where the average proportion of shared alleles between and within populations X and Y ( \( \overline{P}_{SA_{B}} \), \( \overline{P}_{SA_{X}} \), \( \overline{P}_{SA_{Y}} \) respectively) is computed overall possible combinations of individuals sampled.
