#Honestly punet squares are one of the best things I have ever learnt about

Hi welcome to I think about things too much sometimes today the genetics of Bending in Atla

Okay the bending genome is 100% a recessive gene otherwise there would be far more benders than there is, meaning in Katara and Sokka’s family both Kya and Hakoda have the recessive gene resulting in a 50 50 chance that their child would be a bender (Which happens obviously) so that is the stranded for families with bending child and non-bending parents. 

Now we look over to the Fire nation royal family (Who are all benders) all the royal family have the two recessive allies needed to bend now because Ursa’s is a non-bender but did have a bending ancestor (You know Roku) and the fact that both Zuko and Azula are benders she carries the gene, now if you take Ozias double recessive and Ursa’s Dominant recessive there would have been a 1 in 4 chance that Zuko or Azula would have been a non-bender.

Okay, next is, is there Dominant genes inside the recessive gene? What does that mean? If you have two bending parents for example a Water bender and an Earth bender both have the recessive-recessive meaning it their child will be a bender, what bender would they be? Is Water bending the dominant bending gene or is it the earth bending gene? and I don’t know there isn’t enough data to draw a proper conclusion on that, so I’ll leave it.
