WebMar 21, 2013 · The First Genetic-Linkage Map. March 21, 2013. One hundred years ago, in 1913, Alfred H. Sturtevant helped lay the foundations of modern biology by mapping the relative location of a series of genes on a chromosome. Chromosomes are the long threads in the cell's nucleus that had been discovered in the 1880s in cells undergoing division; … WebBecause chromosomal maps are based on estimates of physical distance, they are considered to be physical maps. The number of base pairs within a band can only be estimated. Until recently, even the best chromosomal maps could be used to locate a DNA fragment only to a region of about 10 Mb, the size of a typical band seen on a chromosome.

Linkage analysis is a genetic method that searches for chromosomal segments that cosegregate with the ailment phenotype through families. It can be used to map genes for both binary and quantitative traits. Linkage analysis may be either parametric (if we know the relationship between phenotypic and genetic similarity) or non-parametric. Parametric linkage analysis is the traditional approach, whereby the probability that a gene important for a disease is linked to a genetic mar… WebApr 26, 2007 · Scientists studying mosquitoes have produced the first chromosomal map that shows regions of chromosomes that activate -- and are apparently evolving -- in …
