7.10 Variation in Populations
in AP Biology
Variants that are well adapted to one environment may not be well adapted to another environment.
To Think About:
How does genetic diversity of a species or population affect its ability to withstand environmental pressures? What makes genetically diverse populations resilient? What determines if an allele is deleterious or adaptive?

Answer the Following Questions:

- Why are populations that are more genetically diverse more likely to survive environmental changes?
- Whether or not an allele or a phenotype provides an advantage to the organism depends on the ____________________. If the _____________________ changes, a previously advantageous allele can become disadvantageous.
