    A certain autosomal recessive condition is seen in approximately 1 in every 50 people, but is symptom-free. If a male and female possibly carry the gene, what is the probability that they have a diseased child?

    answer: ( 1/50)(1/50)(1/4)= .01%

    I thought what question says is the probability of being homozygous recessive is 1/50. Therefore the probability of q is square root of 1/50.

    I am confused about is it saying the probability of that allele is 1/50 or the homozygous genotype is 1/50 :confused:

    Yeah don't worry about this one, it's been asked before. I doubt the actual DAT will be this confusing/ambiguous. Many other people thought the same thing you did (like me), so you're not alone in your confusion.
