Expert Solution & Answer

Answer to Problem 1.1A

Tube	Starch	Sugar
1. Amylase Solution	Absent	Absent
2. Starch Solution	Present	Absent
3. Starch-Amylase Solution	Absent	Present

Explanation of Solution

The starch is a polymer of multiple glucose moieties connected via a-1,4 glycosidic linkage. It is broken down into simple sugars during the process of digestion. The process of breaking down of starch is catalyzed by an enzyme known as amylase.

In tube 1, only the enzyme is present, but it needs substrates (starch) to convert it into its simpler constituents. Therefore, starch and sugar will not be found in this test tube.

In tube 2. Only the starch is present, and amylase is absent. Therefore, starch will not be broken down and thus sugars will not be present in this tube.

In tube 3, both starch ad amylase is present, therefore, the amylase will breakdown starch into simple sugar. Thus, sugars will be detected in this tube.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
