other family studied, one man, now

a number of years, but there has been 
no noticeable effect on his hair, which 
is very heavy and coarse. 
Returning to chart 1, II 7 and I 5 
both had very thin fine hair, but re- 
tained it until very late in life. I 5

amount of moderately fine hair; IV 9 
has exceptionally heavy, coarse hair 
like his father’s; IV 10 has not quite a 
normal amount of moderately coarse 
hair; IV 11 has very heavy, fine hair,
