| dc.description.abstract | A genetic map of the bovine X chromosome was constructed from ten X-linked microsatellite markers scored in a reciprocal backcross and F2 Angus x Brahman beef cattle population. The map spanned 132.2 cM or approximately 4.7% of the 2,800 cM bovine genome, and the three pseudoautosomal microsatellite markers spanned 4.8 cM and 6.9 cM of the bovine X and Y chromosomes, respectively. The microsatellite markers had PIC values ranging from 0.35 to 0.85 and HET values ranging from 0.22 to 0.86. An interval mapping analysis was used to search for quantitative trait loci on the bovine sex chromosomes. Genes associate with six experimental traits including marbling score (MARB), quality grade (QG), fat percentage of steaks (FAT), overall tenderness of steaks (OTEND), amount of connective tissue within steaks (CTIS) and kidney-pelvic-heart fat (KPH) were located on the bovine X chromosome. An overdomina FAT, MARB and QG was located in the pseudoautosomal region, the gene associated with KPH was located close to microsatellite marker BM6017. The difference between Angus and Brahman homozygotes at the loci affecting MARB, QG, FAT, KPH, OTEND and CTIS was 0.81, 0.85, 1.16, 0.12, 0.62 and 0.47 phenotypic standard deviations, respectively. | en |
