Abstract

Congenital dyserythropoiosis and dyskeratosis occur within certain lines of Polled Hereford cattle. Eighty-nine of 90 alleles in 45 affected calves had a mechanism in which they could be identical by descent from an identified common ancestor. The line allele may have been a recurrence of the mutation, or the mutation may have occurred earlier in the breed's history and been distributed throughout the breed by the extensive use of several ancestors. No evidence of disease has been identified in sire and dams of affected calves, suggesting that the allele is not acting in a dominant or incompletely dominant manner. Even distribution of cases between sexes suggests that the disease is not sex linked or sex influenced. A higher degree of inbreeding in the affected calves and temporal and spatial features that separated individual cases also suggest a genetic cause. Segregation ratios were not significantly different from those of the hypothesized simple autosomal recessive inheritance.
