Question

Blood type in humans is an example of a genetic locus where more than one genetic interaction is at play. Below is a that represents one child per row, and gives the phenotype, or blood type, of each child's parents.

Using what you learned in lecture, please indicate the possible blood types (also the phenotype) for each child. HINT: first fill out the two blank columns of the possible genotypes that both Mom and Dad can have.

Child number	Mom's blood type	Mom's possible genotype(s)	Dad's blood type	Dad's possible genotype(s)
1	A		B
2	A		AB
3	A		O
4	AB		O
5	O		O
6	B		O
7	B		AB
