Both parents are heterozygous for the gene(Aa)
If either of the parents were aa, they would be albino also. If either was AA the child couldn't be aa

Both parents have to be heterozygous dominant. The punnet square would look like this:
AA Aa
Aa aa
the only way to have an albino child is if both parents contribute a recessive allele.

non albino means they are carriers for the recessive alleles. Aa
If both parents are heterozygous then there is a 25% chance they will have an abino child eg
-----A--------a
A---AA-----Aa
a---Aa-----aa (albino)
