Subject: where can I get info on human bone differences?

I have always been interested in forenics- how can we tell from bones the 
gender( if we only have a skull) and what is there that marks the bones as 
caucasan, african etc? I would also like to know the answer to a piece of 
information in my physical antro class- its been years so i dont know the 
particulars- one of our native Amer tribes share DNA? Blood type? with another 
distint group. where can I learn more about these kinds of questions( I'm to 
old to get my PHd now!!) please answer. Thank you
