Fig. 7From: Performance of Swedish Warmblood fragile foal syndrome carriers and breeding prospectsEffect of selection against the lethal allele. The average frequency of carriers over simulation replicates, with error bars reflecting the 5 and 95 percentiles. The scenarios are (1) complete selection against carrier sires (i.e., all carrier sires are excluded), and (2) when the carriers among the sires in either the 10 or top 100 of each breeding goal are included regardless of their carrier statusBack to article page
