It wouldn't surprise me if the element ones are Rinnegan mutations too. Just as the Rinnegan is better than the sharingan but the sharingan's best versions have some advantages, perhaps the element kekkei genkai are more specific variants of it's ability to let people use elements.Of course, we don't necessarily know that all of them come from the Sage's line at all. It may just be the kind of thing that happens with the genetics in the world. Rinnegan did pop up on it's own after all. They also seem the simplest conceptually- the genes that make someone naturally aspected to one element or another exist for multiple elements (or are otherwise linked) in the same person.
I think both Haku and his mother had Ice, so it seems they can pass down, but don't necessarily do so.
Hm, we don't really know of any clans revolving around a combined element kekkei genkai, unlike the eye ones which seem to always pass down. (Amateur generic hour to follow) So it may they are normally recessive and only show up occasionally.
It could be that there's a general set of genes for element aptitude, some dominant and some recessive, and kekkei genkai happen when two (or in Mei Terumi's case, three) of them all manage to activate in one person. So (using upper-case for dominant and lower case for recessive, and Wi / wi = Wind, E / e = Earth, Wa / wa = Water etc.) someone might need WaE to have mokuton, while Wae would just be a water user who could also use Earth (like perhaps the Second Hokage, his brother).
Or even more complex than that. We know it's not just one pair, since it's possible to have three.
But whatever the case, it seems likely that while the eyes can be passed over in their entirety, elements are *probably* a combination of the parent's genetic traits in respect to elements, so there's more chance involved and a lot of people likely have an incomplete set needed for the kekkei genkai.
Could be entirely possible. After all, the Sage was the first one to use all 6 nature types and the first one to use ninjutsu. He then passes down his genes and knowledge, and through time, certain mutations occur that allow select individuals the ability to manipulate and combine two elements.
Yeah, I remembered the Haku thing. His mother was a carrier of the trait required for Hyouton, which means that Hyouton is probably a recessive trait. That's likely the case for all the other elemental kekkai genkais.
So far, all we know is that every single ninjutsu user has an affinity to a certain element, which means that genetically, they all have the genes for one type of nature transformation.
Or, it could be that the ability to combine elements could be a co-dominant trait, and the ability to use other elements in addition to your own, is simply just due to training and/or genius.
Sharingan is slightly weird though. To date, we haven't been shown any female Sharingan wielders. So it's entirely possible that the allele for the trait is carried on the Y-chromosome. Then there's the fact that the activation of the Sharingan requires an intense emotional experience which is why not all Uchiha have the Sharingan.
Byakugan has been shown in both males and females, and no such emotional experience is required.
