Abstract:
A range of mathematical models and error distributions was used to examine the validity of linear regression methods for the calculation of lethal gene equivalents. Because of the restricted span of inbreeding coefficient F values available in human studies and the limited number of data points, equivalent results were obtained with all combinations tested. It was concluded that linear regressions should be employed only for the detection of significant inbreeding effects in man and that their application to the estimation of lethal gene equivalents was not warranted.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
