Today in class we started off by taking notes on genetic variation, genetic drift, and speciation. genetic drift is changes in the gene pool of a small population due to chance. We then learned about variation in Grasshopper legs by working on Lab 40. With our lab groups, we were asked to measure the length of 5 grasshoppers' femurs. This data was then used to find the average femur length from all the grasshoppers. The different lengths of femurs represent variation-a change in gene frequency.
The homework for tonight is to finish lab 40, read 19.2, and the T.V. ad that is due on feb. 28.
