Parent-of-origin effects in sheep: impact on the data fit, explanatory power of the model and theoretical accuracy of the breeding values.

Abstract excerpt

Although parent-of-origin effects have long been recognized, little is known about their association with growth-related traits in sheep. Specially, it is unclear whether their presence in the model can increase the theoretical accuracy of the breeding values or not. In this study, the effect of including parent-of-origin effects in the genetic evaluation model on the data fit, explanatory power of the model and...
