Re: Simian crease and hereditiy

If you all three seem to be normal, without any other dysmorphic trait, 
which can be properly evaluated by a good clinical geneticist, and the 
most important without clinical complains, there's nothing to worry. About 
the parenthood doubt it can be checked through DNA testing, very quickly 
and very safely. The eyes color sometimes might be misleading, again, a 
good clinical geneticist should be consulted. All the best,
