The results of the cross between two Drosophila melanogaster with long wings and red eyes—the wild type
(a) Determine the curved-wing allele autosomal recessive, autosomal dominant, sex-linked recessive, or sex-linked dominant.
(b) Determine the lozenge-eyed allele autosomal recessive, autosomal dominant, sex-linked recessive, or sex-linked dominant.
(c) The genotype of the female parent.
(d) The genotype of the male parent.
Introduction:
Drosophila melanogaster are the fly species that are also known as vinegar fly. Further, due to the accessible features of the Drosophila, it is used as a model system extensively used in laboratories for the research purpose. The results of the cross between two Drosophila melanogaster with long wings and red eyes—the wild type phenotype is given in table below.
Females | Males |
600 long wings, red eyes | 300 long wings, red eyes |
200 curved wings, red eyes | 100 curved wings, red eyes |
300 long wings, lozenge eyes | |
100 curved wings, lozenge eyes |

- 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?arrow_forwardDraw 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 closearrow_forwardName 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).arrow_forward
- 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.arrow_forwardNow 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)arrow_forwarda. Which drug is the most potent? a,b,c,d,e b. Which drug has the highest efficacy?arrow_forward
- 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?arrow_forwardNonearrow_forwardQuestion #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…arrow_forward
