Age-dependent quantitative trait loci affecting growth traits in Scottish Blackface sheep.

Animal genetics - 1 Apr 2009

Hadjipavlou G, Bishop S C

Abstract excerpt

To dissect age-dependent quantitative trait loci (QTL) associated with growth and to examine changes in QTL effects over time, the Gompertz growth model was fitted to longitudinal live weight data on 788 Scottish Blackface lambs from nine half-sib families. QTL were mapped for model parameters and weekly live weights and growth rates using microsatellite markers on chromosomes 1, 2, 3, 5, 14, 18, 20 and 21. QTL...
