This 31-slide teaching PowerPoint presentation covers 1.A.2 (Phenotype Variations) and 1.A.3 (Genetic Drift) 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 presentation itself contains minimal information as it is 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.
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:
1.A.2 - Population Phenotypes:
a. Environments change and act as selective mechanism on populations.
b. Phenotypic variations are not directed by the environment but occur through random changes in the DNA and through new gene combinations.
c. Some phenotypic variations significantly increase or decrease fitness of the organism and the population.
d. Humans impact variation in other species.
1.A.3 - Genetic Drift:
a. Genetic drift is a nonselective process occurring in small populations.
b. Reduction of genetic variation within a given population can increase the di#erences between populations of the same species.
