Learn how to set up and solve a genetic problem involving multiple alleles using ABO blood types as an example!

Paul Andersen explains the importance of blood types in blood transfusions. He starts with a brief discussion of blood antigens and antibodies. He describes how the ABO differs from the Rh blood type. He shows you how to solve simple...

You’re probably aware that your blood can be A, B, AB or O, but it turns out that blood types can get a lot more complicated than that! *We made a mistake in the credits of this video: The writer of this episode was Alane Lim.

Do you know your blood type? Even more - do you know what it means? By the end of this video, you'll understand the physiology behind blood types. You'll also understand the significance of the ABO and Rh Blood Grouping Systems.

Across life on Earth, blood comes in red, blue, green, purple, even clear. But why? And what makes your blood different from mine? This video will teach you everything you need to know about the strange world of blood—what it does, why...

This video explains the ABO blood group system which is important for blood transfusion compatibility. The video describes the four blood types and how they are determined by the presence or absence of specific markers on red blood...

Blood grouping is based on the presence of specific antigens—A, B, and H—on red blood cells, encoded by the ABO gene system. Individuals with blood type A have A antigens and anti-B antibodies, B has B antigens and anti-A antibodies, AB...

There are many things to keep in mind when choosing your life partner. One such thing is the blood group. We don’t think of this at first, but differences in blood groups can lead to complications. More specifically, these problems can...

This video explains the concept of codominance, where two alleles for a gene affect the phenotype equally. The video provides examples of codominance in ABO blood groups in humans and feather color in hens. It explains the different...

Humans inherit two alleles for each gene, and their interaction determines how traits are expressed—homozygous if both alleles are the same, and heterozygous if they differ. In complete dominance, one allele masks the other; in...

Multiple allele traits are controlled by a single gene with more than two allele variants, as seen in the ABO blood group system, which involves the alleles IA, IB, and i. The six possible genotypes result in four blood types, with IA...
