Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can
study here
.
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.
1. Way more offspring are produced than by sexual reproduction
Theory

2. Change in alleles due to random chance

10. Another method designed to sort female sperm form male sperm; goes by size of sperm; females are bigger than male sperm
plasmid
Frequency dependent selection
Asexual reproduction
Micro - sort
11. Theory of a stable - nonevolving population in which frequency of alleles do not change; only occurs in large - isolated populations with random mating - and no natural selection or mutations
Heterozygote Advantage
'Pharm' animals
Asexual reproduction
Hardy- Weinberg equilibrium
12. Differences in appearances between the sexes
Theory
Sexual dimrphism
Modes of Selection
Stabilizing
13. Selects for the middle and against the extremes
Frequency dependent selection
Bottleneck effect
Stabilizing
DNA fingerprinting
14. All species on earth are fixed; no changes - no new species - no extinction
Historical Context of evolution
Charles Darwin
Genetic drift
Intrasexual selection
15. The more common a trait becomes the more likely it will be selected against
Frequency dependent selection
Asexual reproduction
Bottleneck effect
Recombinant DNA technology
16. Heterozygous chromosomes have an affect on an individuals genetics/alleles
Heterozygote Advantage

Advantages of Recom. DNA tech
17. A group of interbreeding organisms living in the same place at the same time

20. The idea that characteristics can enhance an organisms survival
Genetic drift
Theory
Heterozygote Advantage
Adaptation
21. Traits that are neither advantageous nor disadvantageous; there is no selection
Neutral Variation
Disruptive selection
Most organisms are...
Molecular similarity
22. The process of sperm sorting; separating the male sperm from the female sperm; difference told by swimming speed; boy sperm swim faster than girl sperm; Theory might have flaws in it though - only works 50% of the time
Disruptive selection
Natural selection does not make perfect individuals
Stabilizing
Ericson Method
23. Came up with the term catastrophism(sudden events that lead to extinction - but not in todays time)
