WebFeb 4, 2024 · Putative QTL were designated as major QTL if they explained greater than 10% of the observed variation . Peak marker positions for each chromosome (based on LOD score) were used to identify linkage blocks between flanking markers to identify chromosomal regions containing the suspected QTL, according to their physical positions. WebQuantitative trait loci (QTL) with small effects on phenotypic variation can be difficult to detect and analyze. Because of this a large fraction of the genetic architecture of many complex traits is not well understood. Here we use sporulation efficiency in Saccharomyces cerevisiae as a model compl ….
WebMar 11, 2024 · A small-effect QTL can be detected in a very large sample, but such a small-effect QTL is useless in any breeding programs. The final reported variance of a detected QTL is often converted into the proportion of phenotypic variance contributed by the QTL, called the QTL heritability [ 5, 6 ].
