Humans can be one of the four possible blood types Blood type A and B are dominant over type
0. Complete a Punnett square and determine the expected genotypes and phenotypes from
crossing a person who has homozygous type A and a person with type AB

here.

Explanation:

Considering that the allele for type A is IA, that for type B is IB and that of type O as IO,

The genotype for homozygous type A is IA IA and that for type AB is IA IB.

Crossing IA IA × IA IB,

50% IA IA- blood type A

50% IA IB- blood type AB

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.

magnesium is an electrolyte injection commonly used to treat low magnesium levels in your blood. it is also used to prevent or control seizures in women with preeclampsia or eclampsia.
