Genetic linkage map of chicken chromosome 1 from a Brazilian resource population

Abstract: A genetic map provides insight into genome organization and chromosomal location of markers and genes, and is important for quantitative trait loci (QTL) mapping. The objective of this study was to use a Brazilian resource population to construct a linkage map for chicken chromosome 1. Eighty microsatellite markers were tested and 26 informative markers were typed in an experimental F 2 population developed by two generations of crossbreeding between a broiler sire line and a layer line. A total of 649 F 2 ind… Show more

“…In our study, the TCTC map for GGA1 was reanalyzed using 31 microsatellite markers and showed a total length of 491.1 cM, with 13.7 cM average distance between adjacent loci. Two inversions were observed, comparing the results shown here with those from Nones et al (2005): between MCW0208 and MCW0010 and between ADL0183 and LEI0106. However, those authors did not employ the ALL function in the CRI-MAP software; they used the TWOPOINT, BUILD, FLIPS2, and CHROMPIC functions, which could be an explanation for the differences.…”

“…For the TCTC population, Nones et al (2005) had already constructed a 464.1 cM linkage map for GGA1, using 26 microsatellite markers, with an average distance between adjacent loci of 15.0 cM. In our study, the TCTC map for GGA1 was reanalyzed using 31 microsatellite markers and showed a total length of 491.1 cM, with 13.7 cM average distance between adjacent loci.…”

“…Each male was mated to three unrelated females selected randomly to generate 21 F 1 families, with approximately 100 chicks per family, in 17 incubations, totalizing 2,063 F 2 animals. The construction of the genetic linkage map of chromosomes 6, 7, 8, 11 and 13, used the five informative families indicated in a previous selective genotyping study of chromosomes 1 to 5 in this population (Baron, 2004;Nones et al, 2005;Ruy et al, 2005). TT was selected for various generations for growth related traits, such as body weight, whereas CC was selected for egg production traits .…”
