A case of disputed maternity

It has been alleged that two Gujarati Muslim boys are not the sons of the woman who brought them to the United Kingdom, claiming them to be her sons. The father has recently died, but blood samples from the mother and her four daughters (whose parentage is not in doubt) allowed the paternal genotype to be deduced. Samples were tested for 9 blood-group systems (12 gene loci), 9 red-cell-enzyme systems, 6 serum protein types, 2 HLA loci, and 5 X-chromosome probes. There was no evidence of non-maternity of the two boys in any of these systems. The odds that the woman who claims to be the boys' mother, rather than any random Gujarati Muslim woman, is indeed the mother of the older boy are fourteen million to one, and that she is the mother of the younger boy five million to one.
