ENVS240 Midterm 1 Review

Which of these macromolecules are directly involved in the Central Dogma?

• Carbohydrates

• Nucleic acids

• Fats & lipids

• Proteins

ATPs belong in which category?

• Carbohydrates

• Nucleic acids

• Fats & lipids

• Proteins

Phenotypes are MOST DIRECTLY associated with which category?

• Carbohydrates

• Nucleic acids

• Fats & lipids

• Proteins

Inbreeding becomes an issue for populations because....

• mutations increase in the population due to non-random breeding.

• heterozygosity decreases in the population due to non-random breeding.

• homozygous recessive genotypes increase in the population because of non-random breeding.

• deleterious alleles are expressed more because of non-random breeding.

This causes mutations.

• Natural selection

• Gene flow

• Genetic Drift

• Mutation

• Inbreeding

How populations adapt.

• Natural selection

• Gene flow

• Genetic Drift

• Mutation

• Inbreeding

Perhaps the most essential connection between the microevolutionary mechanisms and macroevolution.

• Natural selection

• Gene flow

• Genetic Drift

• Mutation

• Inbreeding

All mutations result in the translation of different proteins.

• True

• False

Draw a figure (a graph!) that represents the relationship between population size and genetic diversity. Add "adaptive potential" to the figure too, possibly as a second axis.

What are you most nervous about for the exam?
