If you have type A blood, what are your possible genotypes? ………………………………. If you have type B blood, what could your genotypes be? ……………………………….
If you have type AB blood, what must your genotype be? ……………………………….
If you have type O blood, what must your genotype be? ………………………………
Pattern of inheritance ………………………………

Explanation:

1.Their genotype is either AA or AO

2.blood type B could have a genotype of either BB or BO

type AB or type O is more informative.

3. Someone with blood type AB must have both the A and B alleles. The genotype must be AB.

4.Someone with blood type O has neither the A nor the B allele. The genotype must be OO.

Pattern of inheritance;

There are five basic modes of inheritance for single-gene diseases: autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, and mitochondrial.
