Name III. Data Analysis & Assignment for Drosophila Genetics Lab Print out your spreadsheet and staple it to this section or upload it to Canvas as directed by your instructor. PART A - Dominant/Recessive Inheritance Analysis of the serrate cross 1. What percentage of F2 offspring had the serrate mutant phenotype? 2. Based on this, does the serrate mutant allele display dominant or recessive inheritance? 3. Was the percentage exactly what you expected? If not, how can we determine whether the difference is just due to chance or whether it means that something else is affecting the percentages? Let's do a Chi square analysis, comparing the observed numbers with those you would have expected for the apparent mode of inheritance. Enter observed numbers into the spreadsheet provided by your instructor and perform all calculations. (Do the calculations in the spreadsheet; don't use a calculator and then type in your answers. This is the equivalent of showing your work!) What $\chi^2$ value did you obtain? 4. Determine if your observed results are significantly different from the expected numbers using the critical values for $\chi^2$ (table on page 6-29). Use one degree of freedom. What P value did you obtain? >P> 5. Did the $\chi^2$ analysis support the mode of inheritance that you proposed? If not, propose an explanation for what might be affecting those numbers. (Note: assume that the mode of inheritance that is best supported by the percentages is in fact correct, and that there is something else going on in addition that is altering the percentages. What is it?)
8.13 Find the voltages at all nodes and the currents through all branches in the circuit of Fig. P8.13. Assume $|V_{BE}| = 0.7$ V and $\beta = \infty$.
Consider a half wave rectifier circuit with a filter capacitor is fed by a sinusoid input, $V_{in}$ with 5M? load, whose input and output wave is given in Figure 03. The semiconductor material used to build the diode is germanium. V 50V $t_1$ $t_2$ 20ms $V_{out}$ $V_{in}$ 1V Figure 03 t (d) The discharging time of the filter capacitor depends on the time constant, $\tau$=RC. Now, if the time constant, $\tau$ is chosen to be 0.5 then how does it affect the discharging of the output? Give your explanation with proper diagram.

From 1D Schrodinger equation, $-\frac{\hbar^2}{2m}\frac{d^2\Psi}{dx^2} + V\Psi = E\Psi$, find the energy state with the lowest eigenvalue. Explain what is a quantum size effect and prove why the smaller the quantum dot, the shorter the wavelength the absorbance?
