Chapter 6, Problem 17MC

when we collect fish or mussels we record a variety of biological information, including but not limited their sex, length, weight or a scale or finray or other tissue sample. Why do we do this, and what information are we hoping to obtain from these measurements and taking these samples?

Draw a rough sketch of the control and experimental data using a normal dose/response curve plot: i.e. % of total bound ligand vs. concentration. Indicate Kd and Bmax on this sketch. You don’t need to use exact numbers, but the relative proportions should be close

Name something that could be happening to glutamate transporters that could have this effect on glutamate transport (i.e. the difference in glutamate transporters between control and experimental conditions). (Bonus: if you can also guess what the experimental condition is).

a. For the control condition, calculate Kd. Include units and show your work. b. For the control condition, calculate Bmax. Include units and show your work.  c. For the experimental condition, calculate Kd. Include units and show your work. For the experimental condition, calculate Bmax. Include units and show your work.

Now draw a rough sketch of what the control data might look like if in addition to the specific binding, there was also a considerable amount of nonspecific binding (again using a normal dose/response curve)

a. Which drug is the most potent? a,b,c,d,e b. Which drug has the highest efficacy?

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW).  If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?

None

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…
