Assume both freckles and dimples are dominant traits. Freckles are controlled by a single gene with two alleles (F & f), and dimples are controlled by a single gene with two alleles (D & d). Assume the genes for freckles and dimples are found on different chromosomes and assort independently of each other. Simeon does not ave freckles, but he does have dimples. His wife, Virginia has both freckles and dimples. (She is very cute.) Their son, Fred, has neither freckles nor dimples. Based on the above information, answer the following questions. A. What is the probability that Simeon and Virginia's next child will have freckles but not dimples? B. If Simeon and Virginia have two more children (not twins), what is the probability that one child will have dimples but no freckles and the other child will have both freckles and dimples ?

C) translocation of the c-myc proto-oncogene. D) amplification of the N-myc gene. 4) The translocation that places the transcription factor Tel at the amino terminus of the PDGF receptor converts PDGFR to an oncogene by: Group of answer choices A) activating the tyrosine kinase domain in monomeric form. B) increasing the transcriptional activation capability of Tel. C) forming Tel dimers that produce unregulated signals for proliferation. D) constitutive repression of the fusion protein.

Problem 1 (15 pts.): A message signal $v_m(t) = 6 \cos(4\pi 10^5t) + 4\cos(8\pi 10^5t)$ modulates the carrier $v_c(t) = 10\cos(2\pi f_ct)$, with $f_c = 1MHz$, to produce a DSB signal $v(t)$. a. (4 pts.) Determine the time domain expression of the DSB signal (show all the derivations). b. (4 pts.) Draw the spectra of the message signal $v_m(t)$ and the modulated signal $v(t)$. Label frequencies and corresponding amplitudes of each spectral line. What is the required transmission bandwidth for $v(t)$? c. (3 pts.) What filter should be used if it is desired to generated the upper SSB signal using the above DSB signal? Draw the spectrum of the SSB signal. What is the required transmission bandwidth of the SSB signal? d. (4 pts.) For the message and carrier signals given above, write the expression of a conventional AM modulated signal with m=0.5. Draw its spectrum.
