Hey guys,
I was going over Bio from destroyer and I just can't figure out these two questions even after having read the descriptions.
" A certain autosomal recessive condition is seen in approximately 1 in every 50 people, but they are symptom free. If a male and female are both carriers of this gene, what is the probability that they have a diseased child?"
The answer is: 0.01%
I honestly have no idea how they got to this. They say each parent has 2% of a chance to carry the gene... but i thought each parent is a carrier? *confused*
Second Question
"The frequency for the allele for an autosomal recessive trait is 1 in 2500 in white Americans. What is the heterozygote frequency?"
The answer they gave is 4%. Can someone explain how to use HW here? I would reaallly appreciate it. Thanks
