Estimate the Gene Effect and Type by Orthogonal Regression Approach
Identifying the type and estimating the effect of genes controlling the quantitative trait is very useful to select the breeder breed and produce the livestock. In traditional quantitative genetics, the gene effect causing the variation of quantitative trait is researched as a whole body. The molecular marker technique provides an approach to analysis the gene characteristic of single gene. To QTL analysis, it is the first thing to determine the number of QTL controlling the quantitative trait, and then locates the QTLs and estimates their effects. In this paper, avoiding the QTL mapping, the molecular marker orthogonal regression approach is used to research the quantitative trait controlled by polygene. The result shows, this approach can estimate the genes relative effect, assess overdominant genes overdominant coefficient and identify the genes type efficiently, and thus, can probably be used to the fields of animal breeding, selection, production and predict the affinity and combining ability of animals, etc.
