The distribution of these individual proportions about the mean proportion \u03bc is not known for any large hybrid population in man. It is of interest to know whether the population variance of individual proportions (\u03bci) can be estimated from the variation between different, independent estimates of the mean proportion (\u03bc).This possibility was tested with data on Negroes of the <a href=\"http:\/\/en.wikipedia.org\/wiki\/Oakland,_California\" target=\"_blank\">Oakland, California<\/a> area, by the use of some of the principles of analysis of variance. Even with a large sample and the useful <a href=\"http:\/\/en.wikipedia.org\/wiki\/Duffy_antigen_system\" target=\"_blank\">Duffy blood-group system<\/a> to indicate admixture, almost no information about the population variance of individual proportions is provided by between-sample variation in estimates of \u03bc. It is concluded that group data on admixture proportions usually do not give useful information about the population variance. It is further concluded that a recent estimate of this variance by Shockley is in error.<\/p>\n<p>Read the entire article <a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC389614\/pdf\/pnas00087-0271.pdf\" target=\"_blank\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Population Variance of the Proportion of Genetic Admixture in Human Intergroup Hybrids Proceedings of the National Academy of Sciences December 1971 Volume 68, Number 12 pages 3168\u20133169 PMCID: PMC389614 T.
