How to estimate kinship.

abstract：:The populations of the bivalve clam Macoma balthica in the low-salinity Northern Baltic Sea represent an admixture of two strongly diverged genomic origins, the Pacific Macoma balthica balthica (approx. 60% genomic contribution) and Atlantic Macoma balthica rubra (40%). Using allozyme and mtDNA characters, we describe...
