Mapping QTLs on chicken chromosome 1 for performance and carcass traits in a broiler x layer cross
With the objective of mapping quantitative trait loci (QTLs) for performance and carcass traits, an F₂ chicken population was developed by crossing broiler and layer lines. A total of 2063 F₂ chicks in 21 full-sib families were reared as broilers and slaughtered at 42 days of age. Seventeen performa...

| description | With the objective of mapping quantitative trait loci (QTLs) for performance and carcass traits, an F₂ chicken population was developed by crossing broiler and layer lines. A total of 2063 F₂ chicks in 21 full-sib families were reared as broilers and slaughtered at 42 days of age. Seventeen performance and carcass traits were measured. Parental (F₀) and F₁ individuals were genotyped with 80 microsatellites from chicken chromosome 1 to select informative markers. Thirty-three informative markers were used for selective genotyping of F₂ individuals with extreme phenotypes for body weight at 42 days of age (BW42). Based on the regions identified by selective genotyping, seven full-sib families (649 F₂ chicks) were genotyped with 26 markers. Quantitative trait loci affecting body weight, feed intake, carcass weight, drums and thighs weight and abdominal fat weight were mapped to regions already identified in other populations. Quantitative trait loci for weights of gizzard, liver, lungs, heart and feet, as well as length of intestine, not previously described in the literature were mapped on chromosome 1. This F₂ population can be used to identify novel QTLs and constitutes a new resource for studies of genes related to growth and carcass traits in poultry. |
