Abstract:
In a female White Polled Heath a congenital shortening and abnormal bending of the tail was observed. The trunk appeared to be shortened and almost quadratic. However, further findings could not be ascertained in the general clinical, neurological and orthopaedic examination. Maceration of the trunk skeleton showed vertebral fusion in several segments of the vertebral column and a wedge-shaped vertebra of the cervical spine, causing slight scoliosis. In addition, several ribs were fused. Exogenic causes such as drugs or viral infections during pregnancy were unlikely, whereas hereditary could not be ruled out.

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...
