Vital Signs @ McKendree – Thursday: The Blood Part 1
Today, our scientists delved into the study of blood type and the genetics that help determine it. Students first discovered the physical basis behind the ABO blood type group, analyzing different antigens. In the lab, they attempted to determine the blood type of different samples by creating antibody reactions.
The analysts-in-training also learned the basics of Mendelian genetics, discovering how blood type traits are inherited and why some are dominant over others.
Ask your student:
How many total possibilities are there for blood type? (there are 8 including both genes: A+/-, B+/-, AB+/-, and O+/-)
What is one method to predict the blood type of the offspring when you know that of the parents? (use a Punnett square)
