NettetMagnus Dehli Vigeland, in Pedigree Analysis in R, 2024. 9.1.5 Multipoint Analysis. A practical challenge in linkage analysis is the limited information carried by a single marker. Recall from the example in Section 9.1 that heterozygosity at the marker locus is a prerequisite for inferring recombination. This is not well supported by the SNP markers … NettetLinkage analysis has been facilitated greatly by the discovery of highly polymorphic regions of the human genome, revealed with the techniques of modern molecular biology. Di-, tri- and tetra-nucleotide repeats and the use of polymerase chain reaction (PCR) have all contributed to the availability of highly polymorphic markers, and microsatellites now …
