genome-duplication

2 articles

Genome duplication, or polyploidy, occurs when an organism's cells carry more than two complete sets of chromosomes, a condition arising from errors in cell division or hybridization events. It is remarkably common in plants and has been a major driver of plant evolution, enabling increased genetic diversity, adaptation to new environments, and the emergence of novel traits. Studying genome duplication helps researchers understand crop domestication, improve breeding strategies, and unravel how plants cope with genomic stress and complexity.
