Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can

.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

14. Forms that show how an organisms anatomy change over time
Transitional forms
Theory
Reproductive cloning
Intersexual selection
15. Takes the gene from a needed product - puts it into another organism (usually bacteria) and it will make duplicates of the product

Molecular similarity
Stabilizing
Germinal choice
Modes of Selection
19. The screening of embryos for genetic disorders; done in In Vitro fertilization(fertilization in a petri dish); PGD removes one cell from the embryo and screens it genetically; embryos with disorders are discarded - ones without are kept and implanted
Founder effect
Asexual reproduction
Preimplantation Genetic diagnosis (PGD)
Population
20. All species on earth are fixed; no changes - no new species - no extinction

Evolution
21. A subset of a population colonizes a new area
Most organisms are...

Evolution
23. Traits that are neither advantageous nor disadvantageous; there is no selection
Hutton

26. Subset of natural selection that increases the likelihood of mating specifically
