In humans phenylketonuria and Lactose Intolerance are both autosomal recessive traits. If 2 individuals who are heterozygous for both traits marry and have children, what is the chance of having a child with PKU and Lactose Intolerance?
I think it is 1/16 but I'm not really sure.. .Is this correct?
Another problem I'm having difficulty with is...
If a heterozygote for PKU and Lactose Intolerance marries someone with both traits, what is the chance of having a child with both traits?
I know the cross would be PpLl X ppll but I don't know how to work the problem out.
I used
P= non carrier of PKU
p=PKU carrier
L=non Lactose intolerant
l=lactose inolerant gene
