Genetics is the study of inheritance and variation in living organisms. One of the fundamental concepts in genetics is the idea of alleles, which are different forms of a gene that can result in different traits. In some cases, a gene may have multiple alleles, meaning there are more than two possible forms of that gene. This is known as multiple alleles.
When it comes to blood types, the ABO blood group system is a classic example of multiple alleles. In this system, there are three alleles that determine blood type: A, B, and O. Each person inherits two of these alleles, one from each parent, which can result in four possible blood types: A, B, AB, and O.

Understanding Blood Type Inheritance
When it comes to blood type inheritance, the ABO blood group system follows a specific pattern. The A and B alleles are dominant over the O allele, and the A and B alleles are co-dominant with each other. This means that if a person inherits an A allele and a B allele, they will have type AB blood. If they inherit an A allele and an O allele, they will have type A blood. If they inherit a B allele and an O allele, they will have type B blood. And if they inherit two O alleles, they will have type O blood.
Using a genetics worksheet to explore the concept of multiple alleles in the ABO blood group system can help students grasp these complex inheritance patterns. By working through problems and scenarios, students can gain a deeper understanding of how genes and alleles interact to determine traits like blood type.
