✦ Synopsis

Data from two surveys performed in Brazil and involving 5,719 persons have been subdivided into three subsamples (one with cousin and sib controls). The totals led to estimates of B (abnormal equivalents per gamete) around 0.5, of A (the damage in a noninbred population) around 0.01-0.02, and of B/A from 14 to 77. No statistically significant difference was found between whites and nonwhites (mulattoes and Negroes). Inbreeding seems to disclose a predominantly mutational load.
