One way to overcome inbreeding depression is by periodically introducing new genetic variation in a process known as outcrossing, where members of the breed are mated with individuals from outside the breed. ❋ Unknown (2009)
This is known as '' [[inbreeding depression]] '', and '' outcrossing '', or '' outbreeding '' ❋ Unknown (2009)
'' outcrossing '', or '' outbreeding '' genetic elements and can result in heterosis. ❋ Unknown (2009)
Ecological correlates of male outcrossing ability in a simultaneous hermaphrodite snail. ❋ Carl Zimmer (2009)
Temperature-determined outcrossing ability in wild populations of a simultaneous hermaphrodite snail. ❋ Carl Zimmer (2009)
Plants have many adaptations that increase the likelihood of outcrossing. ❋ Unknown (2009)
Higher than ever pesticide use, and herbicide resistance, outcrossing to other species, and herbicide resistant wild radish, oats and skeleton weed in Australia has increased in paddocks that Round-Up is used on, the weed loves it! ❋ Unknown (2009)
Human populations that could benefit from outcrossing include the hemophiliac royal families of Europe, and Ashkenazic Jews Before the Holocaust, Galician parents would parade Jews of marriageable age in carriages from tiny shtetl to tiny shtetl to open up the gene pool. ❋ Ann Althouse (2008)
Plants and animals…like humans have all sorts of mechanisms to promote outcrossing, and the study of how natural selection produces outcrossing goes right back to Darwin. ❋ Unknown (2007)
It might require some relaxation of some breed standards to allow a certain degree of outcrossing to effect the changes, but could well be worth the effort. ❋ Stanley Coren (2000)
Since most nitrogen fixing fodder trees are outcrossing, seed from trees dose together is more likely to be paternally related - received pollen from the same tree. ❋ Unknown (1996)
Most nitrogen fixing fodder trees are thought to be outcrossing (an exception is L. Ieucocephala which is largely selfing). ❋ Unknown (1996)
Populations in Cameroon show levels of outcrossing from 50-100%, with variation in a population throughout the flowering season. ❋ Unknown (1996)
BREEDING SYSTEMS: Pigeonpea (2n = 22) is mostly self-pollinating, but a range of 3 - 95% outcrossing has been reported. ❋ Unknown (1996)
LEUC and tetraploid varieties of DIVE are self-pollinating, while all others are outcrossing. ❋ Unknown (1990)
