WebGenetic mapping was practiced for nearly four decades prior to the demonstration that DNA was the hereditary molecule, taking advantage of the phenomenon of "genetic linkage" explained by Morgan using "visible markers." A visible marker is simply a mutation in a particular gene, which imparts a discrete, easily-identified phenotype to an organism. WebComparative genetic linkage mapping using genetic and genomic resources from related species such as B. rapa and A. thaliana has shown to be very useful in the genetic and physical fine mapping of a number of agronomically important gene loci, e.g. for disease resistance (Mayerhofer et al., 2005), male sterility (Xie et al., 2012; Lu et al., 2013) and … ray and barbara dalio foundation https://rooftecservices.com
