-- Included in 3.A - Inheritance Package --
This 18-slide teaching PowerPoint presentation covers 3.A.4 (Non-Mendelian Patterns) in the AP Biology (2015) curriculum. Each slide includes the 'Essential Knowledge' being covered as well as key terms that students should make note of (editable).
The presentations themselves contains minimal information as they are intended to be used with teacher guidance. There are 'Video' slides throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.
I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the AP Bio Essential Knowledge objectives. The remaining class time is spent reinforcing the knowledge or working on activities geared toward the 'Learning Objectives'.
**These presentations are based on the AP Biology Course Guide and does not follow any textbook
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

The Essential Knowledge covered includes:
3.A.4 - Non-Mendelian Patterns
The inheritance pattern of many traits cannot be explained by simple Mendelian genetics.
a. Many traits are the product of multiple genes and/or physiological processes.
- 1. Patterns of inheritance of many traits do not follow ratios predicted by Mendel’s laws and can be identified by
quantitative analysis, where observed phenotypic ratios statistically differ from the predicted ratios.
b. Some traits are determined by genes on sex chromosomes.
- Sex-linked genes reside on sex chromosomes (X in humans).
- In mammals and flies, the Y chromosome is very small and carries few genes.
- In mammals and flies, females are XX and males are XY; as such, X-linked recessive traits are always expressed
- Some traits are sex limited, and expression depends on the sex of the individual, such as milk production in
female mammals and pattern baldness in males.
c. Some traits result from nonnuclear inheritance.
- 1. Chloroplasts and mitochondria are randomly assorted to gametes and daughter cells; thus, traits determined
by chloroplast and mitochondrial DNA do not follow simple Mendelian rules.
- 2. In animals, mitochondrial DNA is transmitted by the egg and not by sperm; as such, mitochondrial-determined
traits are maternally inherited.
