Part 3: 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 ratio of phenotypes? 5. Based on these results, what would you expect if you were looking at a cross of 5, 10, or 20 independently sorted genes? 6. Why is it so expensive to produce a hybrid plant seed? 7. In certain bacteria, an oval shape (O) is dominant over round (o) and thick cell walls (T) are dominant over thin (t). Show a cross between a heterozygous oval, thick cell walled bacteria with a round, thin cell walled bacteria. What are the phenotypes of the F1 and F2 offspring?

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.

if you listed your answers right then i believe your answer is b.
