Red-green color blindness is due to an X-linked recessive allele in humans. A widow’s peak (a hairline that comes to a peak in the middle of the forehead) is due to an autosomal dominant allele.
Consider the following family history:
The man’s father had a straight hairline, as did both of the woman’s parents.
Use the family history to make predictions about the couple’s children.
Drag the correct label to the appropriate location in the table. Not all labels will be used.
1. If the couple has a child, what is the chance that it will be a son with a widow's peak?
2. What is the chance that any son the couple has will be color blind with a straight hairline?
3. What is the chance that any daughter the couple has will be colorblind with a widow's peak?
4. Suppose the couple had a daughter with normal color vision and a widow's peak. What is the chance that she is heterozygous for both genes?

From the perspective of adaptation, does it matter if traits under selection arise in another species versus already occurring as standing genetic variation or as a new mutation within a lineage? What implications does this have for the origins of genetic novelty in a species by genetic modification (e.g., GMOs)?

Problem 2. You wish to determine the energy content per gram and Calories per serving of a chocolate chip cookie and a banana bread slice from the Student Union to decide which is less “fattening.” The intact cookie and banana bread slice you are analyzing weigh 72.501 g and 69.003 g, respectively. Before you can analyze the samples, the calorimeter heat capacity must be determined. It is known that combustion of 1.000 g of benzoic acid releases 26.44 kJ of heat = 26.44 kJ. Thus, you combust 1.000 g of benzoic acid in a constant-volume calorimeter and record a temperature increase of 2.52 °C.
2a. From the data given above, determine the heat capacity of the constant-volume calorimeter. To receive credit, you must show all work in a legible, highly organized manner.
2b. Now you take a 5.688 g sample of the chocolate chip cookie and burn it in the same calorimeter. During the combustion, the temperature of the water in the calorimeter increases by 11.81 °C. For the chocolate chip cookie, calculate the energy content in kJ/g and the Calories per serving. Please remember, you must show all work in a legible, highly organized manner.
2c. Finally, you take a 4.904 g sample of the banana bread and run it in the same calorimeter. During the combustion, the water temperature in the calorimeter increases by 12.29 °C. For the banana bread slice, calculate the energy content in kJ/g and the Calories per serving. Don’t forget, you must show all work in a legible, highly organized manner.
2d (3p). Based on the above Problem 2 data, is the chocolate chip cookie or banana bread slice less “fattening” in terms of the energy content in kJ/g? What about in terms of the Calories per serving? In complete sentences, clearly justify your reasoning citing the evidence.

Tim and Rebekah have five girls and they are planning to have their sixth and last child in the fall. Tim is very concerned that his bloodline will be lost as he has only daughters and no sons. He is the only boy in his family and so he feels that unless he has a son, his name will not be passed on to the next generation. Tim reads about a new technology that allows you to test embryos before implanting to select for various traits, including sex. He feels that it might be worth it not to leave it to chance to see if the last child will finally be a boy.
Consider the above scenario and determine whether you feel Preimplantation Genetic Diagnosis technique should be used by Tim and Rebekah to select for a boy.
