Fine Mapping of Milk Production QTL on BTA6 by Combined Linkage and Linkage Disequilibrium Analysis

From: Journal of Dairy Science | Date: March 1, 2004| Author: | Copyright information

ABSTRACT

Combined linkage and linkage disequilibrium analysis were used to refine the position of a previously detected QTL affecting milk production traits on bovine chromosome 6. Through a series of single- and multitrait and single- and multipoint QTL analyses, the QTL could be positioned to a 7.5-cM interval surrounded by the markers BMS2508 and FBN12. The most significant results were found for fat percentage and protein percentage. This effect seemed to be caused by a QTL allele embedded in one specific marker haplotype that caused a reduction in fat and protein yields and a concomitant ...
