Hi there everyone, been a while since I came on here. Some of the names are new to me. Didn't have internet access when I changed jobs, but I got myself a laptop and I'm raring to go... The diet's been crap since I stopped my regular posts on here,...

Does anyone know of a website or can advise me if it possible to see what a parents blood type is? If parent A is O+ and the child is O+ what are the possible types of blood groups for parent B?
