Access Code (located on the lid of your lab kit): Pre-Lab Questions Assumptions: · There are approximately 3,000,000,000 base pairs in the mammalian genome (genes constitute only a portion of this total). · There are approximately 10,000 genes

Post-Lab Questions 1. How similar are the observed phenotypes in each replicate?   2. How similar are they if you pool your data from each of the five replicates?   3. Is it closer or further from your prediction?   4. Did the results from the monohybrid or dihybrid cross most closely match your predicted
