Evolution and Natural Selection • Why is Geographic Isolation so important to the process of natural selection? • Explain the process of Speciation • What does it mean to have a common ancestor? • Genetics problem and Natural Selection • What is the difference between Homologous and Analogous structures?
Classification • If two specific organisms are very similar genetically…should they be classified together? Explain! • Scientific name problem

Mendelian Genetics • Define in your own words • Incomplete Dominance • Codominance • Sex Linked • Dominant • Recessive
Mendelian Genetics What trait will most likely be observed in all offspring of the above set of parents? Show your punnett square!!! A Green feathers B Yellow feathers C Long beak D Short beak
MendelianGeneticsCo Dominance If you mix white paint (W) with red paint (R) you would get Pink paint…right? Show a punnett square that proves this!
Experimental Design A student placed a disk of filter paper in each of the following solutions: disinfectant 1, disinfectant 2, disinfectant 3, and distilled water. While the four disks were soaking in their respective solutions, she streaked a sterile nutrient agar dish with a culture of E. coli bacteria. Then, she placed each disk carefully onto the nutrient agar dish, placed the lid on the dish, taped it shut, and incubated the dish at 37ºC for several days. Figure 19-4 shows how the nutrient agar dish looked on Day 1 and Day 4.
