Re: homozygotis

I don't know how reputable they are, but there are several companies
that claim to assist with this kind of thing:

http://www.genassist.com/
http://www.dnatesting101.com
http://www.reproductivegenetictesting.com/
http://www.synergene.net/

For more, just do a web search on "genetic profile".

Again, I know nothing about any of these firms. Many are likely to be
disreputable, since it's easy to fake stuff like this.

Better yet, ask your doctor/hospital/HMO for some referral names.

I doubt you'll be able to deduce much on your own or via a simple web
page. Relatively few traits are reducible to classical Mendelian pairs
of dominant/recessive alleles. Even human hair color and eyes often
aren't that obvious. What of green eyes?

Remember too, that with all the phenotypic data on your grand/parents
(six folks), it's hard to conclude much as to which genotypic alleles
they had. Unless a large fraction of the family have the recessive
trait(s), it's tough to know whether someone who has a dominant trait is
homozygous or heterozygous for the two (or more) alleles that cause that
trait (e.g. Gb and GG).
