Blood Types
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...

Punnett Squares and Sex-Linked Traits
Explore inheritance when carried on the X chromosome with the Amoeba Sisters! This video focuses on how to do general Punnett square problems that involve traits on the sex chromosomes (X and Y chromosomes). We do want to point out...

Mega Genetics Review
Ready to review how to do different types of Mendelian and Non-Mendelian Punnett square problems with The Amoeba Sisters? This video reviews one-trait / monohybrid crosses, two-trait / dihybrid crosses, incomplete dominance, codominance,...

Alternate Genetic Crosses
“Alternate Genetic Crosses” models incomplete, codominance, and multiple allele genetic crosses in order to determine the genotype and phenotype of the possible offspring.

Blood Types
Young scientists learn the importance of knowing blood types and their compatibility. The instructor in the video explains each type of blood and their antigens and antibodies, and then differentiates between AB blood and Rh blood types....

Multiple Alleles (ABO Blood Types) and Punnett Squares
Whatever you do in life, always give 100 percent—unless you are donating blood. A video explains how to solve Punnett squares with multiple alleles, in this case blood types. It includes what happens if the wrong type is added, which...

Non-Mendelian Genetics
Any pattern of inheritance that does not follow Mendel's laws uses non-Mendelian inheritance. The video explains this type of genetics with many guided practice problems. It covers incomplete dominance, codominance, and sex-linked traits.
