Answer:

The type of inhertiance pattern shown by the child with type AB blood is called INCOMPLETE DOMINANCE.

Step-by-step explanation:

INCOMPLETE DOMINANCE is the ability of two contrasting alleles to interact and produce a heterozygous phenotype that is different from the two homozygous phenotype.

According to the principles of Mendel, genes are either dominant or recessive; the dominant expressing itself in homozygous or heterozygous state. i.e., the children should have all with blood type A or type B.

But in the case being discussed, a child with AB does not agree with Mendel's principles all because neither blood type A nor type B is fully dominant over the other, hence, type AB, a different phenotype would emerge
