|---|---|
| In situ conservation |
A conservation method that attempts to preserve the genetic integrity of gene resources by conserving them within the evolutionary dynamic ecosystems of the original habitat or natural environment. (cf. Ex situ conservation) |
| In vitro collection |
A germplasm collection maintained as plant tissue ranging from protoplast and cell suspensions to callus cultures meristems and embryos. |
| Inbreeding |
The mating of genetically related individuals or between relatives. Breeding through a succession of parents belonging to the same stock. Also called endogamy or self-breeding. (cf. Outbreeding) |
| Indehiscent fruit |
Fruit that does not open at maturity (see also achene). |
| Ingroup |
A putatively monophyletic group that is the prime subject of a cladistic analysis. |
| INIFAP |
Instituto Nacional de Investigaciones Forestales, Agricolas y Pecuarias, Mexico (website) |
| Inter Simple Sequence Repeat |
A molecular marker technique that targets variation in the DNA between two microsatellite loci. |
| Inter-retrotransposon Amplified Polymorphism |
(IRAP) A molecular marker technique that targets variation in retrotransposon insertion sites. |
| Interbreeding species concept |
A philosophy and set of methods that define species almost entirely on the ability of species to exchange genes naturally or artificially as assessed by artificial crossing programs studies of mechanisms to facilitate gene flow and biological isolating mechanisms. |
| Internal Transcribed Spacer |
(ITS) A sequence of nuclear ribosomal DNA commonly examined for phylogenetic analysis consisting of two spacer regions intercalated between the 18S, 5.8S, and 26S genes. |
