Genome

fluorescence in situ hybridization (FISH)

Biology; Genome

A physical mapping approach that uses fluorescein tags to detect hybridization of probes with metaphase chromosomes and with the less-condensed somatic interphase chromatin..

amplification

Biology; Genome

An increase in the number of copies of a specific DNA fragment; can be in vivo or in vitro. See also: cloning, polymerase chain reaction.

polygenic disorder

Biology; Genome

Genetic disorder resulting from the combined action of alleles of more than one gene (e.g., heart disease, diabetes, and some cancers). Although such disorders are inherited, they depend on the ...

forensics

Biology; Genome

The use of DNA for identification. Some examples of DNA use are to establish paternity in child support cases; establish the presence of a suspect at a crime scene, and identify accident victims..

animal model

Biology; Genome

See: model organisms.

polymerase chain reaction (PCR)

Biology; Genome

A method for amplifying a DNA base sequence using a heat-stable polymerase and two 20-base primers, one complementary to the (+) strand at one end of the sequence to be amplified and one ...

fraternal twin

Biology; Genome

Siblings born at the same time as the result of fertilization of two ova by two sperm. They share the same genetic relationship to each other as any other siblings. See also: identical twin.
