Science / Genetics / Linkage: The proximity of two or more markers (e.g., genes, rflp markers) on a chromosome: the closer together the markers are, the lower the probability that they will be separated during dna repair or replication processes (binary fission in prokaryotes, mitosis or meiosis in eukaryotes), and hence the greater the probability that they will be inherited together.
Science / Genetics / Linkage Disequilibrium: Where alleles occur together more often than can be accounted for by chance. Indicates that the two alleles are physically close on the dna strand. MORE
Science / Genetics / Linkage Map: A map of the relative positions of genetic loci on a chromosome, determined on the basis of how often the loci are inherited together. Distance is measured in centimorgans (cm). MORE
