Linkage data on MN and the Hb beta locus.
A sample of 28 informative families was studied for linkage between Hb beta and MN. Values of the neuterized recombination fraction from these and other families from the literature excluded a recombination fraction of less than .30 between these loci. Our results support different recombination values for males and females (theta equals .34 abd .50, respectively). A simple approach to estimate the sample size required as well as a study of the relationship between sibship size and sample size under conditions of loose linkage are also presented.
