Abstract: An F2 experimental population, developed from a broiler layer cross, was used in a genome scan of QTL for percentage of carcass, carcass parts, shank and head. Up to 649 F2 chickens from four paternal half-sib families were genotyped with 128 genetic markers covering 22 linkage groups. Total map length was 2630 cM, covering approximately 63% of the genome. QTL interval mapping using regression methods was applied to line-cross and half-sib models. Under the line-cross model, 12 genome-wide significant QTL and … Show more

“…Ambo et al (2009), studying the same population of broilers, mapped QTL for body weight traits at 35 and 41 days of age on the GGA4, exactly in the same chromosome region where QTL for tibia width and weight were mapped (MCW0240-LEI0063). Within this chromosome region, Baron et al (2011) mapped QTL for drums and thighs; Schreiweis et al (2005) for tibia area, length, and width; and Sharman et al (2007) for tibia bone mineral density, and femur weight.…”

“…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).…”

“…In a previous study, Ambo et al (2009), working with an experimental F 2 population derived from a cross between a layer and a broiler line from Embrapa, mapped a QTL for body weight at 35 and 42 days between microsatellite markers MCW0240 (198.7 cM) and LEI0063 (235.2 cM) in chicken chromosome 4. In a different study with the same population, Baron et al (2010) mapped a QTL for percentage of thighs and drumsticks in the same region of chromosome 4. The study of this QTL region allowed the identification of 2 candidate genes potentially associated with traits of economic interest: fibroblast growth factor binding protein 1 (FGFBP1) and fibroblast growth factor binding protein 2 (FGFBP2).…”
