Consider the following two genotypes: AABB, aabb where A and B are dominant and a and b are recessive.
1. What is the genotype of the F1 progeny from an AABB x aabb cross?2. Construct a Punnett Square of the F1 self-cross (i.e., F1 x F1). What are the genotypic ratios from this testcross? What are the phenotypic ratios?3. Construct a Punnett Square of the F1 genotype with the AABB parental. What are the genotypic ratios from this cross? What are the phenotypic ratios?4. Construct a Punnett Square of the F1 genotype with the aabb parental. What are the genotypic ratios from this cross? What are the phenotypic ratios?5. If you had an organism that was A-B- and wanted to determine its exact genotype, which cross would you use? Explain your answer.
sketch the chromosomes of the parents and the F1. analyse interference and say what you think of its significance.
Assume you are attempting to determine if the new DNA sample you have just received contains linear or circular molecules. Digestion using either RsaI or SauI alone produces two fragments.
Suppose if you can purchase corn grain or sorghum for $320 per ton as fed for energy, which is the better buy and why? The lab results indicate that the corn is 87 percent DM and has 3.16 Mcal.
A 0.02 M weak acid solution was measured to have a pH of 4.6 determine the [H+] in the solution and compute the acid dissociation constant,
Based on the data, propose a hypothetical biochemical explanation for the colors of the flowers in the F2 progeny. Again, explain your reasoning.
Discuss how do the results of this experiment relate to the role yeast plays in baking? What would you expect to see if the yeasts' metabolism was slowed down?
Suppose if equal amounts of Na2HPO4 and NaH2PO4 are mixed in water, compute the resulting pH. The pKas of phosphoric acid are 2.1, 7.2, 12.4.
How is MPF involved in one or more of checkpoints. A chemist wishes to create an organic molecule non-acidic.
Down syndrome is the result of an extra 21st chromosome in humans. In the process of meiosis for the mother, give all possible stages where it could lead to an offspring with Down syndrome,
Explain what is meant through a negative feedback loop and how these work in terms of regulating a metabolic pathway. provide an example of a negative feedback loop in the glycolytic pathway.
Grace heard on the evening TV news that the deep population in her state had been increasing rapidly in the past few years and it was common knowledge that deer walked the streets at night.
In order to perform a fluorescence experiment, you need to seed a 4-well chamber slide with 60,000 cells in each well. To prepare for the cell count, you transferred twenty uL of cell suspension into thirty uL of trypan blue.
