Sex Linkage: The condition in which the inheritance of a sex chromosome is coupled with that of a given gene; e.g., red-green color blindness and hemophilia in humans. Traits located on the X-chromosome.

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.

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

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).

Gene Mapping: Determination of the relative positions of genes on a dna molecule (chromosome or plasmid) and of the distance, in linkage units or physical units, between them.

Polymorphism: Difference in dna sequence among individuals that may underlie differences in health. Genetic variations occurring in more than 1% of a population would be considered useful polymorphisms fo . . . View Full Definition

Secondary Winding: Winding which is not connected to the power source, but which carries current induced in it through its magnetic linkage with the primary winding.

Deletion Mapping: The use of overlapping deletions to localize the position of an unknown gene on a chromosome or linkage map.

Restriction Fragment Length Polymorphism (RFLP): A heritable difference in DNA fragment length and fragment number; passed from generation to generation in a codominant way.
