AP Biology Chapter 18 - Evolution

QuestionAnswer
gene pool includes all alleles for all the loci present in the population
allele one, two, or more forms of a gene
genotype organism's full hereditary information
phenotype organism's actual observed properties like development and behavior
genetic equilibrium a population whose allele and genotype frequencies don't change from generation to generation
fitness relative ability of a given genotype to make a genetic contribution to subsequent generations
population genetics study of genetic variability within a population and of the forces that act on it
genotype frequency proportion of a particular genotype in the population
phenotype frequency proportion of a particular phenotype in the population
allele frequency proportion of a specific allele of a given genetic locus in the population
locus (loci) fixed position on a chromosome, like the position of a gene
Hardy-Weinberg principle allele and genotype frequencies don't change from generation to generation (no evolution is occurring) in a population at genetic equilibrium
Hardy-Weinberg principle (5 conditions required). Mating is ___ random in the population.
Hardy-Weinberg (conditons). There are no net ___ mutations that change the allele frequencies.
Hardy-Weinberg (conditions). Population ___ is large.
Hardy-Weinberg (conditions). Individuals do not ___ migrate between populations.
Hardy-Weinberg (conditions). Natural selection ___ does not occur.
inbreeding the mating of genetically similar individuals that are more closely related
microevolution change in allele or genotype frequencies within a population over successive generations
mutations unpredictable changes in DNA, are the source of new alleles
Mutations increase the genetic variability acted on by natural selection.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
