QTL Experiment in Brief

Animals: 940 lambs from 5 half-sib families;selective genotyping (22 top, 22 bottom per sire); genome screen 203 microsatellites; all offspring then genotyped for chromosomes 1, 3, 4, 5, 8, 12, 13, 22 and 23

Breeds associated:
n/a

Design: outcross; 2 natural pasture challenges

Analysis: worm counts and fecs log transformed (ln(x+c) where x=count and c=unit count); Nematodirus counts scaled to average s.d. after log transformation total IgE log transformed least squares interval mapping - Haley-Knott regression
