Yоu mаy heаr stоries аbоut siblings who have completely different skin tones (see photo below), even though they have the same biological parents. Is there any possibility that these stories are actually true (i.e., is there any chance whatsoever that this is genetically possible)? Explain your answer. To receive full credit, your explanation must include: (1) the genotypes of the parents and (2) a demonstration that you understand how the skin tone trait is inherited.
In the experiment yоu did lаst week, yоu were аble tо sepаrate a mixture of three components: sand (mostly SiO2), salt (NaCl), and ammonium chloride (NH4Cl). The separation was in three steps: Step 1: First, two evaporating dishes were weighed (Dish A and Dish B). Then, the sample mixture containing the three components was placed into Dish A, weighed again, and then heated. Upon heating, the NH4CL component in the sample vaporizes out of the rest of the sample leaving only NaCL and SiO2 left. After heating, the sample was allowed to cool. Step 2: First, you weighed the cooled sample after step 1. Next, you dissolved the sample in water in Dish A then separated the water from Dish A into a second dish (Dish B). The water dissolves NaCl but not SiO2 because it is insoluble. The insoluble SiO2 was left in Dish A. Dish A was heated to dryness then cooled to room temperature. After cooling, Dish A with dried sample was weighed again. Step 3: Finally, you heated Dish B to boil off the water and to leave behind only the dissolved NaCl. Dish B with the dried sample was weighed again. Using this information, fill in the missing data below. Use only numbers and you must keep proper significant figures for full credit. Begin Step 1 Weight of Dish A: 40.321 grams Weight of Dish B: 41.233 grams Weight of Dish A + sample (before step 1): 43.332 grams Weight of total sample: [A] grams Weight of Dish A + sample (after step 1): 42.520 grams Calculate the %NH4Cl in sample: [B]% (represented as a percent) Begin Step 2 Weight of Dish A + Dry insoluble sample: 40.919 grams Calculate the %SiO2 in sample: [C]% (represented as a percent) Begin Step 3 Weight of Dish B + Dried sample: 42.944 grams Calculate the % NaCl in sample [D]% (represented as a percent)
