 The sugarcane genome is highly similar to the sorghum genome, with most of the genetic material being collinear. This suggests that the two species share a common ancestor, and that the polyploidy of sugarcane did not lead to any significant changes in the number of genes present. Additionally, the fact that the sorghum genome can serve as a template for assembling much of the genetic DNA of the autopolyploid sugarcane genome indicates that there may be fewer genes lost than expected from polyploidy.
