Evolution- genetic change

QuestionAnswer
Describe how Natural selection on single-gene traits can lead to changes in allele frequencies and thus to evolution. organisms of one color may produce fewer offspring than organisms of other colors
Describe what is meant by directional selection the range of phenotypes shift as some individuals fail to survive and reproduce while others succeed.
Describe what impact stabilizing selection has on a population keeps the successful phenotypes and removes the more severe phenotypes
Describe what impact disrupting selection has on a population causes organisms with intermediate traits reproduce less and allows organisms with more extreme traits reproduce more.
Define genetic drift by chance a individual in a small population that carries a certain allele may leave more descendants than others.
Describe how a founder effect can happen allele frequencies change as a result of migration of a small subgroup of a population
State the Hardy-Weinberg Principle genetic variation remains constant from generation to generation
How do you know when a population hits genetic equilibrium allele frequencies remain constant and do not change

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.
