IPA: /ˈbækˌkrɔsɪŋ/
KK: /ˈbækˌkrɔsɪŋ/
The process of breeding a hybrid organism with one of its parent organisms or a similar individual to enhance certain traits or characteristics.
Backcrossing is often used in plant breeding to improve disease resistance.
Backcrossing → It is formed from "back" (meaning in the reverse direction) and "crossing" (from the Old English "cros", meaning to intersect or cross). The term refers to the process of crossing an organism with one of its ancestors or a similar organism, effectively going back in the genetic lineage.
Think of going 'back' in a family tree and 'crossing' with an ancestor — that's what backcrossing means.
