Have students who are confused about biology concepts? You might find this helpful.
In biology, I often find students confused about concepts of complete dominance, incomplete dominance, and codominance types of pattern of inheritance.
I use a simple analogy to help students understand these concepts. I ask them to match the type of inheritance pattern to one of the following scenarios:
- a red curtain made of thick fabric covering a white curtain behind it;
- a red curtain made of thick fabric with different size holes covering the white curtain; or
- a see-through red curtain covering the white curtain behind it.
Students not only pick up on the concept right away, but they retain it as well.
