marker locus
1Marker assisted selection — or marker aided selection (MAS) is a process whereby a marker (morphological, biochemical or one based on DNA/RNA variation) is used for indirect selection of a genetic determinant or determinants of a trait of interest (i.e. productivity,… …
2Marker — A piece of DNA that lies on a chromosome so close to a gene that the marker and the gene are inherited together. A marker is thus an identifiable heritable spot on a chromosome. A marker can be an expressed region of DNA (a gene) or a segment of… …
3Locus — The place, in Latin.. In genetics, a locus is the place a gene occupies on a chromosome. One locus, two loci. * * * 1. A place; usually, a specific site. 2. The position that a gene occupies on a chromosome. 3. The position of a point, as defined …
4Quantitative trait locus — See also: Epistasis Quantitative traits refer to phenotypes (characteristics) that vary in degree and can be attributed to polygenic effects, i.e., product of two or more genes, and their environment. Quantitative trait loci (QTLs) are stretches… …
5Genetic marker — A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify cells, individuals or species. It can be described as a variation (which may arise due to mutation or alteration in the genomic loci)… …
