The large, splayed leaves closely resemble the feet of an aquatic bird, and are not immediately recognizable as Cannabis. The webbed trait is controlled by a recessive gene: it requires two copies of the allele to express, and if crossed with an ordinary compound-pinnate variety the Ducksfoot will produce non-webbed and webbed offspring in an approximate three-to-one ratio. It is unclear where the first webbed Cannabis genetics originated – although there have been several Hawaiian examples over the years, usually more on the indica side of the spectrum. There are many indicas that exhibit a slight degree of webbing, particularly in very wide-leafed varieties, but entirely fused leaves are much more unusual.
