I'd guess 7, but that's just by looking at the diagram.

Does anyone know, or has anyone figured out the answer to the pedigree question? I have only one question left in my assignment, and that is the one I am stuck on! Help would be greatly appreciated, thank you (:

I got 10 people for the pedigree question, as well.

q(2) = 4/21 = 0.1904761
then you square root 0.1904761 = 0.43643
q = 0.436443

1 - q = p
1 - 0.43643 = 0.563564
p = 0.563564

2pq = (2)(0.563564)(0.436443)
= 0.49

then multiple it by the total amount of individuals
(0.49)(21) = 10.29

so I think it is 10 people
