AbstractThe confirmation of the segregation of experimentally populations is required before their commercial design of such confirmation experiments has the the pedigree while maintaining the power to detect chromosomes of a complex pedigree of 570 Charollais contained a moderately sized half-sib family which was wide level were detected in the half-sib analysis and analysis of the complex pedigree using identity-by-estimation of QTL effects was achieved by fitting all observed in the single QTL models. Both methods of different regions, and the variance components method demonstrates the viability of applying a variance inbreeding.
