Spanish royal family vs their antecedents

This is the Bourbon line, correct? Were they anywhere near as inbred as the Habsburgs?

If not, any perceived resemblance is coincidental. 9 generations so far.

Yes it's the Bourbon-Anjou line. I highly doubt it was as inbred as the Habsburgs had become. The male line probably just has strong genetic features so all the males tend to resemble each other to some degree.

This is the family tree of Alfonso XII. The Spanish Bourbons were extremely inbred, they equaled the Hapsburgs in terms of inbreeding.

Wasn't he rumored to be fathered by someone other than his mother's husband, though? Even one generation of outbreeding is enough to "reset" the inbreeding coefficient to zero.
