mapping quantitative trait loci in livestock using simple regression approach
the availability of the saturated dna marker maps in livestock has made it possible to locate quantitative trait loci (qtl) in these domestic animals. the objective of this research was to investigate the principles of applying the simple regression for qtl analysis in paternal half-sib (phs) design commonly used in livestock species. the theoretical aspects of the simple regression approach fo...
متن کاملMultiple interval mapping for quantitative trait loci.
A new statistical method for mapping quantitative trait loci (QTL), called multiple interval mapping (MIM), is presented. It uses multiple marker intervals simultaneously to fit multiple putative QTL directly in the model for mapping QTL. The MIM model is based on Cockerham's model for interpreting genetic parameters and the method of maximum likelihood for estimating genetic parameters. With t...
متن کاملInterval mapping of multiple quantitative trait loci.
The interval mapping method is widely used for the mapping of quantitative trait loci (QTLs) in segregating generations derived from crosses between inbred lines. The efficiency of detecting and the accuracy of mapping multiple QTLs by using genetic markers are much increased by employing multiple QTL models instead of the single QTL models (and no QTL models) used in interval mapping. However,...
متن کاملQuantitative trait loci mapping of panicle traits in rice
In this study 90 individuals of recombinant inbred lines (RILs) were developed by crossing subspecies of japonica rice cultivar, ‘Nagdong’ and an indica type cultivar, ‘Cheongcheong’. These individuals were used to identify the quantitative trait loci of panicle traits using SSR markers. A genetic linkage map was constructed using one hundred fifty four simple sequence repeat ...
