The condition or state of having six complete sets of chromosomes in a cell, found in certain plants where it can affect growth and reproduction.
From 'hexaploid' + '-y' (condition). This noun form emerged alongside hexaploid in 20th-century genetics as scientists named and studied polyploid plant conditions.
Hexaploidy is actually an evolutionary superpower in plants—while having extra chromosome sets might seem chaotic, it often makes plants stronger, more disease-resistant, and more adaptable to their environment.
