Bikini Bottom: Blood Type Genetics and Codominance

The Problem:

Two starfish couples had babies in the same hospital at the same time. Patrick and Patti had

twins: a boy named Paul and a girl named Patricia. Lawrence and Lisa had a girl, Lucy. After

seeing all of the babies, Lisa insisted that the hospital had switched the baby girls, giving Lisa’s

real daughter to Patti. The hospital decided to perform blood type tests for both families to see if

Lisa was right.

The Information:

There are many different ways to classify blood types, but the most common blood type

classification system is the ABO (said “A-B-O”) system. There are four blood types in the ABO

system: Type A, Type B, Type AB, and Type O. These blood types refer to different versions of

carbohydrates (complex sugar molecules) that stick out of the surface of red blood cells.

1. How are Type A carbohydrates depicted in the diagram above?

2. How are Type B carbohydrates depicted in the diagram above?
