Linkage

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.

Linkage Disequilibrium

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

Linkage Map

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

Genetic Linkage Map

Science / Genetics / Genetic Linkage Map: A chromosome map showing the relative positions of the known genes on the chromosomes of a given species. MORE
