pgs 80-81 Allelic Frequency Lab

Procedures

1. Place 50 dark beans and 50 light beans into the bag. 
2. Shake the bag. Remove two beans. These represent 1 rabbit’s genotype (BB or Bb or bb).
3. As you remove pairs of beans, arrange and neatly organize the beans in two columns representing the two possible phenotypes (brown or white).
4. Examine the columns. Remove 25% (every 4th one) of the brown rabbits and 100% (all) of the white rabbits. 
5. Count the number of dark beans and white beans remaining. Record data in your data table.
6. Calculate % of both alleles. Record in your data table.
7. Begin the next generation by placing 100 beans into the bag. The proportions of beans should be the same as the percentages you calculated in Step 6.
8. Repeat steps 3 through 8 collecting data for 5 generations 
9. Graph the % or frequencies for each allele over 5 generations. Use a different color for each allele   (B or b). 

What you need on page 80 (completed with your data) as well as a graph (1 GRAPH 2 LINES) with the % or frequency over 5 generations.  We will complete page 81 next week.
