Root Explanation
Backcross → It is formed from "back" (from Old English "bæc", meaning the rear or reverse) and "cross" (from Latin "crux", meaning a cross or intersection). The term refers to the act of crossing a hybrid organism back with one of its parents to reinforce certain traits.
Memory Tip
