Glossary Term
The process of exchange of genetic material between autonomous replicons, which depends on regions of extensive sequence homology between the participating DNA strands. This process involves double-strand breakage of one participant, resection of the break, and strand invasion, followed by formation, displacement and resolution of the Holliday junction. This process is involved in repairing broken DNA and creating combinations of genes that may be unique from the parent duplexes. Disruptions in this process can result in inviability, premature aging and predisposition to cancers and degenerative diseases.
Indicators
This gene is involved in both homologous recombination and repair of DNA.
Indicators
This gene plays a role in homologous recombination for DNA repair.
Indicators
This gene plays a role in the homologous recombination of double-strand DNA breaks.

Glossary Term
Mutually exclusive alternative forms of the same gene occupying the same locus on homologous chromosomes, differing in nucleotide sequence and governing the same biochemical and developmental process.
Glossary Term
Having two different allelic forms of a gene, one inherited from each parent, on each of the two homologous chromosomes.
Glossary Term
Having two identical allelic forms of a gene, one inherited from each parent, on each of the two homologous chromosomes.
Glossary Term
Nonfunctional DNA sequences that are very similar to the sequences of known genes. Many seem to have arisen as functional gene duplications that subsequently underwent mutation and loss of function. Others are structurally similar to mRNA and seem to have arisen by a reverse transcription event followed by integration into the genome. Some pseudogenes are transcribed and may play a role in regulation of its homologous gene.
