It's pretty funny that you say that because the series itself hasn't actually explained how they work accurately. The common explanation is that they're abilities passed down by blood, but it fails to address elemental Kekkei Genkai entirely which we know for certain are not limited to blood relation. Ice Release is common in both the Yuki clan and the Hidden Snow Village (unrelated to one another), Wood Release has only ever naturally appeared within Hashirama Senju and Moegi Kazamatsuri (unrelated to one another, and contrary to the belief that Wood Release is a Senju thing), Dust Release was taught by Mu to Ohnoki (which is a Kekkei Tota, and neither of them are related to one another.)

If we really need to read about how Kekkei Genkai work, please direct us to where we can actually read accurate information about it. Surely not the wiki, because the wiki page on it starts talking about how it's blood-related but then clarifies in the next paragraph that there are several Kekkei Genkai used by two or more completely unrelated people.

Side Note: Remember the Hidden Stone's Explosion Corps? An elite shinobi team that all specialize in Explosion Release? Clearly, they're not all related by blood.
