Hardy Weinberg Investigation 2 Battling Beetles- Lab Journal Worksheet 1 3. q=.2; p=.8, 2pq=.32 4. 46.8%, p2= .14 5. q2=0.0025 6. q=.02, p=.98, 3.92% 7. p=0.95, q=0.05 8. homozygous dominant individuals= 125, hetrozygous individuals= 250 9. homozygous dominant (straight thumb)=90, heterozygous (straight thumb)= 420, Hitchikers thumb= 490 Think.Write Think about the term Natural selection Write down as many terms as you associate with this term You have 2 minutes go Teams of 3 Assign the following roles Analyzer- will examine the 3 lists and highlight common terms
Recorder- compiles 2 lists one of shared terms and one of unique terms (these are terms that might be shared by 2 of the team but not all 30 Reporter- will after group discussion report to the class the 2 terms that the group should be included on a group list of terms related to Natural selection OPENER What is evolution? What are the basic principles of evolution by natural selection? Are there other mechanisms of evolution? If so, (hint there are) describe them. Scenario 1- Ideal model Generation AA Aa aa 1

In humans, unattached earlobes are dominant, and attached earlobes are recessive. In China, it is reported that 64% of the population exhibit unattached earlobes. Question A: What percentage of the Chinese population exhibit attached earlobes? Question B: What is the frequency of the recessive (attached earlobe) allele in the Chinese population? Question C: What is the frequency of the dominant (unattached earlobe) allele in the Chinese population? Question D: What percentage of the Chinese population are homozygous for the dominant allele (unattached earlobe)? Question E: What percentage of the Chinese population are heterozygous for the earlobe allele? Scenario 4- Sexual Selection Model Generation AA Aa aa 1

Mathematical Modeling: Hardy -Weinberg Complete Part 1- Battling Beetles http://bcove.me/nki9vyom - Watch this video Part 2 the Heterozygous Advantage Malaria and Sickle Cell Part 3 Class activity- mathematical modeling of HW and what happens when we manipulate or violate the 5 conditions Part 4 Using Excel to model H-W and populations. Creating a Lab Journal The purpose of a lab journal is to keep a complete record of all lab activities in this class.
