If an individual has a genotype$I^oI^o$ and $hh$ is he considered to be O or bombay blood group?
Also i read that a person with bombay blood group can donate blood to anyone but can accept only from a person of his blood group, why cant he/she accept blood from O-ve?( is there a H antibody?)

Would that individual be able to accept blood donations from an O-type individual or only from h/h-type individuals?

he can take from O, probably, but if there are H antibodies then , no!
My teacher said that There is no H antibody , but wikipedia says that there are..

Here's a more definitive reference which says there is an H antigen:

http://www.ncbi.nlm.nih.gov/books/NBK2268/

As I read the article more, it says people may have a deficit of the H so I'm looking for a better article to explain it.

I think your teacher meant to say that people with this blood type don't express the H antigen.

I don't feel like trusting that article they say that parabombay blood group have a genotype HH, andthat they have anti-H, which i don't think exists naturally.
I asked another teacher, he said that though there might not be secifically H antibodies, but there will be some reaction, when blood(Hh/HH) is mixed with bombay blood group blood.

For your first question, yes, it is Bombay blood group since O has H not h.
There are anti-H antibodies according to my teacher who swears by Wikipedia :P
