Actually you mentioning breeding just made me think i've never seen anything that looks like a female Falmer...

As for inbreeding -

"Falmer have no right patella (Dead Falmer's right legs can be bent in both directions). This is either a mutation developed over the years, or possibly a result of Inbreeding, or it could be a mistake on the developers part."

Dead bodys go in some odd position in Skyrim could just be the rag doll effect.
