How can a child's blood type be A positive if mom is O positive and dad is AB negative?
If one parent is O positive and the other is AB negative, the child could inherit the A allele from the O positive parent and the Rh factor from the AB negative parent, resulting in the child being A positive. Each parent passes on one allele for blood type and one allele for Rh factor, so different combinations are possible.
Is it more likely for a child to have blue eyes if the mom has brown eyes and the dad has blue?
Yes, it is possible for a child to have blue eyes if the mom has brown eyes and the dad has blue eyes. The inheritance of eye color is a complex trait influenced by multiple genes. Since both parents carry the blue eye gene, it is possible for their child to inherit this trait.

It is possible for a child to have a blood type that is different from either parent if both parents are carriers of a different blood type allele. In this case, the child could inherit the O negative blood type if both parents are carriers of the O negative allele.
What is mom's genotype if her blood type is phenotype A and Dad's phenotype is B and her child's genotype is BO?
This cross AO X BO, would yield that genotype. This cross, AA X BO, would not yield BO. AO X BB would not do it either. So, I assume only AO ( and, from the info given, BO ) is possible for mom.
