Abstract:
Embryonic lethality is a common phenotype that occurs in mice that are homozygous for genetically engineered mutations. These phenotypes highlight the time and place that a gene is first required during embryogenesis. Early embryonic lethality (ie, before and up to mid-gestation) can be straightforward to analyze because the stage at which death occurs suggests why an embryo has failed. Here we summarize general strategies for analyzing early embryonic lethal phenotypes in genetically engineered mouse mutants.

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...
