Hardy-Weinberg equation = 1= P^2 + 2pq + q^2

P^2 = 1/10,000 = 1/100

Then remember P + q = 1 ------> 1/100 + q = 1 (q = 99/100)

Lastly plug back into Hardy-Weinberg Equation as:

2pq = Heterozygote carrier

(2 x 1/100 x 99/100 = 2/100 = 1/50)

link981  I think q should be 1/100. You got p and q mixed up. +
