      alleles are active, so their red blood cells have both the type A carbohydrate and the type B carbohydrate, and they have type AB blood. This is an example of codominance, in which two alleles of a gene each have a different observable effect on the phenotype of the heterozygous individual.

      Blood Types: Cross a heterozygous woman with type B blood with a man with AB blood. Remember: IA, IB, and i are the alleles for blood type. What are the parents’ genotypes? What gametes will come from each parent? Male= Female= Draw a Punnett Square for the cross. What are the genotype ratios of the offspring?

      Your blood type is established before you are born, by specific genes inherited from your parents. You receive one gene from your mother and one from your father; these two combine to establish your blood type. Blood group antigens are either sugars or proteins, and they are attached to various components in the red blood cell membrane.

      Many other genes have multiple alleles, including the human genes for blood type. What are the 4 different blood types? _____ Do you know your blood type? _____ The gene for blood type, codes for a cell membrane protein found on the surface of red blood cells. Each of the three alleles codes for a different protein (A

      Human blood types are determined by genes that follow the CODOMINANCE pattern of inheritance. There are two dominant alleles (IA and IB) and one recessive allele (i). Blood Type (Phenotype) Genotype Can donate blood to: Can receive blood from: O ii A,B,AB and O O AB IAIB O, AB A,B,AB and O A IAIA or IAi AB, A O,A B IBIB or IAi AB,B O,B

      Tell students that antigens and thus, blood type, are determined by the genes that get passed on from someone’s parents. Explain that each parent (and each person) has two blood type genes. This is what’s known as a genotype, or what genes are in someone’s body.

      Blood type is inherited. If both parents carry genes for O and A blood types, each child has probability 0.25 of getting two O genes and so of having blood type O. Different children inherently independently of each other. The number of O blood types among 5 children of these parents is the count X of successes in 5 independent observations ...

      ABO blood type is a trait that is determined by multiple alleles. 5. Polygenic (many gene) inheritance occurs when multiple genes determine the phenotype of a trait. 6. Human eye color is an example of polygenic inheritance. D. Genes and the Environment. 1. Gene are not the only factors that can affect phenotypes.

      These two genes determine your blood type by causing proteins called agglutinogens (a-GLOO-tin-a-gins) to exist on the surface of all of your red blood cells. There are three alleles or versions of the blood type gene: A, B, and O. Since everybody has two copies of these genes, there are six possible combinations; AA, BB, OO, AB, AO, and BO.
