Figure 2: Genome evolution and duplication.
From: The draft genome of a diploid cotton Gossypium raimondii
(a) Phylogenetic analysis showed that G. raimondii and T. cacao separated approximately 33.7 million years ago (MYA). O. sativa, a monocot, was used as the outgroup. (b) Ks distributions of G. raimondii. Yellow line, Ks of all paralogous gene pairs; black line, Ks of tandem gene pairs only; green line, Ks of all except tandem gene pairs.
