Incomplete Dominant and Codominant Traits Worksheet
A two-page instructional activity provides seven Punnett squares for practice in determining genotypes and phenotypes. Each is an example of incomplete dominance or codominance. After your bright biologists have mastered Punnett squares,...

Beyond Mendel: Incomplete Dominance and Codominance
What happens when two cats collide? It depends on whether they exhibit codominance or incomplete dominance! Genetics learners are briefly introduced to the these two concepts and are given a scenario to solve. This handout can be used in...

Were the babies switched? – The Genetics of Blood Types
Human biology or genetics learners apply their knowledge to a unique situation: two newborn baby girls being possibly switched in the hospital. The engaging activity ends with a Punnett squares assignment in which pupils evaluate whether...

A Case of Multiple Alleles - The Inheritance of ABO Blood Type
Here is a sharp presentation on multiple alleles using the classic blood type example. Viewers revisit codominance and dominance and learn that blood type is actually a combination of both. They use Punnett squares to solve blood type...

Incomplete Dominance, Codominance, Polygenic Traits, and Epistasis!
Have you ever met twins or biological siblings with different skin colors? It's not unusual and a helpful video explains why. It includes incomplete dominance, codominance, polygentic traits, and Epistasis, and even explains why...
7 mins 7th - 12th Science
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.
6 mins 9th - 12th Science CCSS: Adaptable
The instructor in a biology video defines and shows examples of incomplete dominance, codominance, epistasis, and multiple alleles. Viewers then explore Thomas Hunt Morgan and his crosses showing the discovery of gene linkage via fruit...
