Nettet17. apr. 2012 · Association mapping (AM), also known as linkage disequilibrium (LD) mapping, is a viable approach to overcome limitations of pedigree-based quantitative trait loci (QTL) mapping. In AM, genotypic and phenotypic correlations are investigated in unrelated individuals. Association mapping is based on the idea that traits that have entered a population only recently will still be linked to the surrounding genetic sequence of the original evolutionary ancestor, or in other words, will more often be found within a given haplotype, than outside of it. It is most often performed by scanning … Se mer In genetics, association mapping, also known as "linkage disequilibrium mapping", is a method of mapping quantitative trait loci (QTLs) that takes advantage of historic linkage disequilibrium to link Se mer The advantages of population based association mapping, utilizing a sample of individuals from the germplasm collections or a natural population, over traditional QTL-mapping in … Se mer • Association (ecology) • Family based QTL mapping • Genome-wide association study Se mer The advantage of association mapping is that it can map quantitative traits with high resolution in a way that is statistically very powerful. Association mapping, however, also requires … Se mer (A) Association mapping in population where members are assumed to be independent. Several standard methods to test for association.
