What actual proof there is that Taiyang is Ruby's father? Biologicaly.

I'm kind of on the side of the theory Qrow in Ruby's real father but for some reason he decided to leave her with Taiyang, maybe to protect her or after death of Summer he didn't feel up to raising her.

I've heard this theory was turned to shreds by fanbase, but why? What is the proof against it?

I have seen someone say that it it was a truth, then Ruby and Yang would be cousins and not sisters... well yeah, and? If both of them would be led to belevie Tainyang is their father and they are sisters... ten by all intents and purposes they would be. Especially if Taiyang was legaly (if there is some infrastructure for this in Remnant) considered Ruby's surrogate father).

And there is issue with the hair... and now I'm starting entire speculation because I do not know only the barest basics about genetics:

- Taiyang is blonde

- Raven is brunette

- Summer is brunette

- Yang is blonde

- Ruby is brunette

- Taiyang + Raven = BLONDE ..... implying Taiyang's gene deciding hair color is a dominant one... especially with the fact that usually dark hair usually overuling the light hair (now this is just something I found on the internet so take it with a grain of salt)

- Taiyang + Summer = BRUNETTE .... well if Taiyang has a strong hair color deciding gene (if there even is such a thing)... than why didn't it work with Summer? Even if she also had a strong gene wouldn't that make Ruby to have at least lighter shade of the hair color and not full strong black?

- even if we switch this and say Raven just had a weak gene, then the similar logic aplies - would't Yang then have her har more dark colored?

I know I'm speculating without a grasp of the "science" here, but I think the logic follows...
