She has a point(centiel)

It would be cute if Jaune turned out to be a lot like her father and that made Ruby feel very fond to him as a result. It's been done before with a daddy's girl growing attached to some guy because his traits and personality resemble the father she loves so much. Buuuuuuut in all those cases, the guy and father in question have no resemblance in looks because, in hindsight, no girl would feel sexually attracted to their own father.

On top of that, we still need to see if Jaune and Taiyang are actually anything alike because if Yang inherited a few things from Taiyang then these two guys might actually be the exact opposite just like Jaune and Yang are too. For example, both Taiyang and Yang shut down after experiencing a huge and hard lost while Jaune didn't stop because of his even though his lost was much bigger. That leaves Jaune and Taiyang being alike only in looks which actually gives Ruby a very good reason to not feel attracted to him.

In summary, Jaune and Taiyang being alike should sink the ship rather than support it... And I did it again with the long analysis.
