introgression

Examples

• All

• The introgression of beneficial genes from wild plants has improved the resilience of crop varieties.

• Disease, competition, and genetic introgression with escapees from aquacultured Atlantic salmon threaten wild stocks in northeastern North America and Scandinavia (Naylor et al. 2005).

• Such actions may substantially reduce transgene introgression and population-level effects.

  Academic text (2008)

• So at what level does introgression cease to be an accelerant to speciation and becomes a retardant?

• Indeed, these authors go on to suggest that introgression may be an important engine for generating genetic diversity in figs, ultimately contributing to high species richness in the genus.

• Carefully managed, limited introgression from a more common taxon may be the only way to genetically rescue one that is endangered (Tailmon et al. 2004, Pimm et al. 2006).

• Our example involves hybridization and introgression of domestic cattle alleles into bison populations, a conservation issue that has already received considerable attention (Halbert and Derr 2007, Vogel et al. 2007).

• Introgression occurs when genes from one species integrate into another species' gene pool through successive crossbreeding.
