Other genetic changes implicated in webbed feet development in avians include reduction of TGF-induced chondrogenesis and reduction of msx-1 and msx-2 gene expression.[12]. 8. According to the. [26] They can also achieve higher speeds underwater due to surface speeds being limited to their hull speed; at this speed, the wave drag increases to the point where the duck cannot swim faster.
