[Analysis of the mode of inheritance for distichiasis in the Elo dog breed using complex segregation analyses].

The inheritance of distichiasis was analyzed in the dog breed Elo using complex segregation analyses. The different hypotheses of monogenic, mixed-monogenic-polygenic and polygenic inheritance as well as a pure environmental model were tested. In further analyses the number of examined Elo dogs per ophthalmologist and the proportion of genes of Eurasian and Old English Sheepdogs were included in the models as covariates.
