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. An accumulation of genetic charges over a certain amount of time

15. Recessive traits persistent to a certain population; recessive alleles hide from selection
Gene flow
Diploiding
Recombinant DNA technology
Theory
16. 1.edits existing variation by using the material it has(variation that exists in population/ no new traits created by natural selection) 2. Has historical constraints(change in old structures) 3. Adaptations are compromises (good for one thing - bad
Reproductive cloning
Directional selection
Natural selection does not make perfect individuals
Intersexual selection
17. The movement of genes between two populations e.g. migration - immigration
Theory
Totipotent stem cells
Embryology
Gene flow
18. Scientific explanation of how life changes over time - science is based off of evidence - science is obtained with observation and testing - science is always open to question
Biogeography
Descent with Modification
Evolution
Stabilizing
19. The idea that characteristics can enhance an organisms survival
Pluripotent stem cells
Adaptation

Sexual reproduction
20. Can make large quantities of product; infection free; less expensive than a natural source

DNA fingerprinting
Molecular similarity
22. Came up with the term catastrophism(sudden events that lead to extinction - but not in todays time)
Disruptive selection
Lyell
Cuvier
Phenotypic variation
23. Related organisms have similar development plans
Gene flow
Embryology
Theory
Bottleneck effect
24. 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
Adaptation
Preimplantation Genetic diagnosis (PGD)
Natural selection does not make perfect individuals
Embryology
25. Another method designed to sort female sperm form male sperm; goes by size of sperm; females are bigger than male sperm
