Abstract:
Six pedigrees including 107 animals of the breed German Brown Swiss were available to test for a single gene conditioning for convergent strabismus with exophthalmus. The regressive logit models of the segregation analysis showed that a major gene model with additively acting genes explained the segregation of affected animals in the pedigrees in the best way. Additionally, polygenic and environmental effects might be of importance in the occurrence of convergent strabismus with exophthalmus.
