Hello, I had a quick question about how the genetics of race mixing works. 

So lets say a 50% Asian 50% white female had a child with a 100% white male. 

would that mean the child would come out, boy or girl, as 75% white, 25% Asian? 

or would it depend on the gender the child is? 

Racial features are determined by a large number of genes in the phenotype. When people of two ethnic/racial backgrounds produce an offspring, the features of the child will depend on which of the alleles is dominant in the every pair. In the end you can have a great range of possible results for the case you're discussing, from the child being showing mostly Caucasian features to him/her taking very little from their dad.

No.
