A person with both A and B pattern genes will have four bands on their chromosomes: the two bands linked to the B pattern, plus the two additional bands linked to the A pattern.
This is because a heterozygous person possesses both the A pattern and the B pattern alleles. The DNA would be split into three fragments in order to investigate the A pattern. The B pattern’s DNA would then be examined after being divided into two pieces. One of the two fragments would match the DNA for the A pattern exactly, whereas the other would be different. The heterozygote would then have four unique bands visible in its DNA, which would be split into four separate parts.
