To determine Possible parentage

/in /by

During a busy night in labor and delivery, several babies may have been mixed up. Preliminary blood tests were performed to determine possible parentage and the results are shown below.

Based on the results of this test, list each individual’s phenotype and all possible genotypes, the antigens present on the RBCs for each blood type, and whether this baby could possibly belong to this set of parents.

Phenotype/ possible genotypes

Mom’s phenotype= AB- /possible genotypes= AB–

Dad’s phenotype= AB+ /possible genotypes= AB++

Baby’s phenotype= O- /possible genotypes= OO–

Antigens on RBCs

Mom’s antigens= A-antigen, B-antigen

Dad’s antigens= A-antigen, B-antigen

Baby’s antigens= none

Is it genetically possible that this baby belongs to this mom and dad?
