$ABO$ blood groups in humans are controlled by the gene $I$. It has three alleles $ I^A, I^B$ and $i$. Since there are three different alleles, six different genotypes are possible. How many phenotypes can occur?
Three
One
Four
Two

$A$ woman is married for the second time. Her first husband was $ABO$ blood type $A,$ and her child by that marriage was type $O.$ Her new husband is type $B$ and their child is type $A B$.
What is the women's $ABO$ genotype and blood type?
How many phenotype and genotypes are possible in ABO blood group systems?
The $ABO$ blood group are controlled by
