Directions: Complete each section of the review by following the directions for each
section.
Part I. Evolution
Standards:
• BI7. a. Students know why natural selection acts on the phenotype rather
than the genotype of an organism.
• BI7. b. Students know why alleles that are lethal in a homozygous individual
may be carried in a heterozygote and thus maintained in a gene pool.
• BI7. d. Students know variation within a species increases the likelihood that
at least some members of a species will survive under changed environmental
conditions.
• BI8. a. Students know how natural selection determines the differential
survival of groups of organisms.
• BI8. b. Students know a great diversity of species increases the chance that at
least some organisms survive major changes in the environment.
• BI8. e. Students know how to analyze fossil evidence with regard to biological
diversity, episodic speciation, and mass extinction.
