Module 6 Mendelian Genetics

Get Focused

Genetics, it seems, does not always play equally with each gender. Have you ever noticed that there are quite a few more balding men than balding women? Perhaps you know of someone who is colourblind. If you do, it is far more likely that they are male than female. Each of these examples indicates that there is more going on than independent assortment. There appears to be a link between the appearance of certain traits and gender.

In this lesson, you will begin to explore inheritance patterns that do not follow Mendel’s laws. You will see how some traits occur more frequently in one gender than the other, and are said to be linked.

In this lesson, the following focusing questions will be examined:

• Why do some traits appear more frequently in one gender rather than the other?

• How did Thomas Hunt Morgan’s work create experimental support for the chromosomal theory of inheritance?

This lesson will take approximately 80 minutes to complete.
