Inbreeding @MarcMillerVM raises the odds that harmful genetic traits will show up in a persons appearance because close relatives share many of the same genes and those recessive problems become more likely to pair together. People affected often display noticeable facial asymmetry where one side of the face sits higher or looks different from the other along with a protruding lower jaw known as the Habsburg jaw that pushes the chin forward creates an underbite and misaligns the teeth sometimes with a thickened lower lip. Dental crowding crooked teeth or gaps appear frequently while the overall face may look broader or more elongated. Many such individuals can show limb or skeletal differences such as clubfoot extra or missing fingers or stiff joints. Skin may appear thinner or more prone to certain conditions and eyes or other features can carry subtle irregularities tied to developmental issues. In extreme cases built up over generations like the Spanish Habsburg dynasty the effects grew severe with a massively jutting jaw a large tongue that caused constant drooling and major trouble speaking or eating leading to a frail weak body and early death as seen in Charles the Second. These changes stem directly from the way repeated close family pairings concentrate the same genetic material across many ancestors so the visible results depend on which specific problems run in that family line but they commonly include uneven features jaw problems reduced size and assorted malformations that set the person apart from typical development.
