Cotton Comparison (IMAGE)
Caption
Upland allotetraploid cotton (right) comes from two extant diploid species, closely related to today's G. raimondii (left) and G. arboreum (middle) or G. herbacieum. The interactions between the genes of these two ancestral species are what give modern-day cotton its best qualities. Somehow, these two different lineages come together to create something greater than the sum of its parts.
