Epistasis: 1) In violets, purple flower color (P) is dominant over white (p), but there is also a gene that determines if that pigment will be expressed in the petals of the flower. If the plant is “cc” then the purple pigment is not expressed in the petals of the flower, and the flower will be white anyway. a. A plant homozygous for both the purple flower and the control gene is crossed with a plant with white flowers and non-expressed pigment. What is the phenotype and genotype of the offspring in this cross? b. If the plants generated in “A” are allowed to self-pollinate, what is the expected phenotypic rations of the resulting offspring?

. Mutations in an autosomal gene in humans cause aform of hemophilia called von Willebrand disease(vWD). This gene specifies a blood plasma proteincleverly called von Willebrand factor (vWF). vWFstabilizes factor VIII, a blood plasma protein specified by the wild-type hemophilia A gene. Factor VIIIis needed to form blood clots. Thus, factor VIII is rapidly destroyed in the absence of vWF.Which of the following might successfully be employed in the treatment of bleeding episodes in hemophiliac patients? Would the treatments workimmediately or only after some delay needed forprotein synthesis? Would the treatments have only ashort-term or a prolonged effect? Assume that allmutations are null (that is, the mutations result in thecomplete absence of the protein encoded by the gene)and that the plasma is cell-free.a. transfusion of plasma from normal blood into avWD patientb. transfusion of plasma from a vWD patient into adifferent vWD patientc. transfusion of plasma from a hemophilia A…

. Neurofibromas are tumors of the skin that can arisewhen a skin cell that is originally NF1+/ NF1− losesthe NF1+ allele. This wild-type allele encodes a functional protein (called a tumor suppressor), while theNF1− allele encodes a nonfunctional protein.A patient of genotype NF1+ / NF1− has 20 independent tumors in different areas of the skin. Samplesare taken of normal, noncancerous cells from thispatient, as well as of cells from each of the 20 tumors.Extracts of these samples are analyzed by a techniquecalled gel electrophoresis that can detect variantforms of four different proteins (A, B, C, and D) allencoded by genes that lie on the same autosome asNF1. Each protein has a slow (S) and a fast (F) formthat are encoded by different alleles (for example, ASand AF). In the extract of normal tissue, slow and fastvariants of all four proteins are found. In the extractsof the tumors, 12 had only the fast variants of proteinsA and D but both the fast and slow variants of proteins B and…
You are a developmental geneticist studying flowering time variation in Arabidopsis. You perform a mutagenesis screen to identify mutants in the photoperiod pathway. You conduct the screen and find two different plants that show the same mutant phenotype. You then use a complementation test. What is the predicted outcome of this test if both phenotypes are caused by mutations in separate genes? recover the wild type phenotype overexpress the gene O recover the mutant phenotype

I. Male Drosophila from a true-breeding wild-typestock were irradiated with X-rays and then mated withfemales from a true-breeding stock carrying the following recessive mutations on the X chromosome:yellow body (y), crossveinless wings (cv), cut wings(ct), singed bristles (sn), and miniature wings (m).These markers are known to map in the order:y - cv - ct - sn - mMost of the female progeny of this cross were phenotypically wild type, but one female exhibited ct and snphenotypes. When this exceptional ct sn female wasmated with a male from the true-breeding wild-typestock, twice as many females as males appearedamong the progeny.a. What is the nature of the X-ray-induced mutationpresent in the exceptional female?b. Draw the X chromosomes present in the exceptional ct sn female as they would appear duringpairing in meiosis.c.
