Body Systems & Evolution
Cover up your body systems chart – can you name all the systems when reading the structures? The functions?
1. In a population of 400 squid, 35 are homozygous recessive for tentacle length.
a) What is the frequency of the dominant and recessive allele?
b) What are the genotype frequencies of the above population?
AA =
Aa =
aa=
2. In a population with 2 alleles, G and g, the allele frequency of g is 0.35. What would be the
frequency of the homozygous dominant individuals if the population is in Hardy-Weinberg
equilibrium?
3. Can you match/explain the types of evolution patterns with their cladogram?
4. Can you match/explain the types of natural selection with their diagram?
5. Similar structures with different functions are called ___________________________. What would be
an example of this?
6. Different structures with similar functions are called ___________________________. What would be
an example of this?
7. What does it mean to have high fitness? Low mortality?
8. Populations become more diverse through…
9. What is genetic drift? Give 2 examples.
10. Give examples of something that might cause a bottleneck effect.
11. Of the 800 insects that dwell on a remote island, 36% are homozygous dominant for having large wings.
How many insects will be heterozygous?
12. If the frequency of the dominant allele is 70%, what would the homozygous recessive frequency be?
13. Compare microevolution and macroevolution:
14. Natural selection acts on a _____________ (phenotype/genotype) however an individual inherits a
____________(phenotype/genotype) from a surviving parent.
15. List the various types of sympatric speciation and give a specific example of each.
16. What is the other type of speciation and give an example?
17. Ultimately, what indicates how fit an organism is?
18. Give example of both positive and negative feedback.
19. What are the 4 types of tissue in the body and what do they do?
