Mnance) Objective: 1. The student will be able to create and complete a Punnett square representing codominance as it relates to their family blood types. 2. The student will be able to analyze data and determine what the possible blood types are for a given set of parents. 3. The student will be able to explain how knowledge of blood types is related to their personal health. Background: Codominance occurs when both alleles in the heterozygote express themselves fully. Because both of the alleles are fully expressed, both alleles are equally emphasized in the genotypic notation. For example, a codominant trait in humans is blood type. The letters A and B that identify blood types refer to the two different carbohydrates that coat the surface of red blood cells. If you have type A blood, you have type A carbohydrate on your red blood cells. Type B blood had type B carbohydrate, Type AB has both carbohydrates, and Type O has no carbohydrates. These alleles are represented by an I, and a superscript A or B to indicate whether the allele codes for type A or B blood. See the chart below for the phenotypes and genotypes of the human blood groups. Blood Groups Phenotypes A B AB O Genotypes IAIA or I^i IBIB or IBI IAIB ii Question: A woman with blood type AB marries a man with blood type O. Is it possible for them to have children with the same blood type as either of the parents? Use a Punnett square to help explain your answer. Create a Punnet square depicting what you believe to be your parents' genotype for blood type in the space below. Explain what information you used to determine each of your parents blood genotypes. Explain how you can use this information to help maintain your personal health?

Objective:
1. The student will be able to create and complete a Punnett square representing codominance as it
relates to their family blood types.
2. The student will be able to analyze data and determine what the possible blood types are for a given
set of parents.
3. The student will be able to explain how knowledge of blood types is related to their personal health.
Background: Codominance occurs when both alleles in the heterozygote express themselves fully.
Because both of the alleles are fully expressed, both alleles are equally emphasized in the genotypic
notation. For example, a codominant trait in humans is blood type. The letters A and B that identify blood
types refer to the two different carbohydrates that coat the surface of red blood cells. If you have type A
blood, you have type A carbohydrate on your red blood cells. Type B blood had type B carbohydrate, Type
AB has both carbohydrates, and Type O has no carbohydrates. These alleles are represented by an I, and a
superscript A or B to indicate whether the allele codes for type A or B blood. See the chart below for the
phenotypes and genotypes of the human blood groups.
