Abstract: An F(2) population established by crossing a broiler male line and a layer line was used to map quantitative trait loci (QTL) affecting abdominal fat weight, abdominal fat percentage and serum cholesterol and triglyceride concentrations. Two genetic models, the line-cross and the half-sib, were applied in the QTL analysis, both using the regression interval method. Three significant QTL and four suggestive QTL were mapped in the line-cross analysis and four significant and four suggestive QTL were mapped in th… Show more

“…This may be the QTL that was detected in the present study at 115 cM, although with a significant additive effect and explaining approximately 2.33% phenotypic variance. These differences may result from adjustment in the infinitesimal genetic effect used in the present study and not considered in the work by Campos et al (2009).…”

“…Some QTLs mapped in this population have been described by Nones et al (2006), Ambo et al (2009) and Campos et al (2009). Procedures seeking to reduce the occurrence of false positives or negatives were not employed in these studies, except of course to adjust the level of type I error to an acceptable level.…”

“…Therefore, genetic studies have been performed to map genes and genomic loci that affect growth, body composition (MCELROY et al 2006, CAMPOS et al 2009, and reproduction traits (TUISKULA-HAAVISTO et al 2002, SASAKI et al 2004, HANSEN et al 2005, SCHREIWEIS et al 2006. If inbred lines of diverse selection lines are used for gene mapping experiments, the probability is very high that different alleles contributing to different traits segregate in the mapping population, and thus these genetic differences can be identified.…”

“…A total of 649 animals were genotyped using 127 microsatellite markers, as previously described (Nones et al, 2006;Campos et al, 2009). Genotyping was carried out using a MegaBACE automated sequencer, and fragment size analysis was performed using the Genetic Profiler software (both GE HealthCare, Little Chalfont, BKM, UK).…”

“…Without adjusting BW42 as a covariate, many QTL regions were mapped for these traits nearby regions associated with BW42 in the same population used in this study (Nones et al, 2006;Ambo et al, 2009;Campos et al, 2009;Baron et al, 2011;Nones et al, 2012). When BW42 was included as a covariate in the model, only three QTL were mapped: two for tibia weight and another for tibia width (Table 3).…”
