Based on what I an seen and read this is how it appears.

Kaguya naturally has Byakugan in both her eyes, her third eye is a highly evolved Sharingan, it became even more advanced by the influence of the Shinju's chakra. If you look at the manga images, her 'Third Eye' is just like Sasuke's left eye. It's not technically a Rinnegan, but something far more formidable.

How did I come to this? Well it basically came down to the fact the Rinnegan was a mutation, so she gave birth to Hagoromo her third eye mutated into the Rinnegan into her son(We still don't know much about Hamura, but we can guess he is probably reasonable for the Byakugan being passed down).

Just to clarify.... This is a THEORY. So don't get your panties in a twist and rant at me.
