Genetics Question About Pedigrees

Post by seabreeze » Sat Oct 25, 2008 4:09 pm

I'm pretty decent at solving probability pedigree questions, but something I'm not sure about...

I know that if the disease in question is a rare disease, then you assume all new individuals coming into the family don't carry the allele for that disease.

But if the disease is NON rare, what happens then? do you just have to calculate both the chances that the individual coming in is a carrier and also the probability if they're not a carrier?
