In a Drosophila salivary chromosome, the bands have a sequence of 12 centromere 3 4 5 6 7 8. a. The homolog with which this is synapsed has a sequence of 1 2 centromere 3 6 5 47 8. What kind of chromosome change has occurred? Draw the synapsed chromosomes at the 4 strand/chromatid stage. If a CO occurs between non sister chromatids between genes 4 and 5 what products will result after CO? Describe the products formed. What will happen during metaphase I and Anaphase I to these chromosomes? At the end of Meiosis II, what are the ultimate products produced and describe. Other chromosomes have sequences as follows: (b) 1 2 centromere 5 6 7 8 (c) 12 centromere 3 4 5 4 5 6 7 8. What kind of chromosome change is present in each? Illustrate how these chromosomes would pair with a chromosome whose sequence is 12 centromere 345678.

A somatic cell has the genotype DdEe. All chromosomes in this organism are metacentric. Show metaphase and the results of mitosis if the D and E locus are linked on the same chromosome in trans configuration. A sexually reproducing organism has the following phenotype DdEeAaTt: The D and E loci are on the same arm of a metacentric chromosome in cis configuration. The A locus is on the long arm of an acrocentric chromosome and the T locus is on a telocentric chromosome. 2.1. What is the haploid number of this organism? 2.2. Using diagrams show a ceii at metaphase of mitosis and show the results of mitosis.
Two chromosomes have the ff. order of genes: Normal A B centromere C D E F G H I Abnormal a b centromere g f e d c h i a. Does the abnormal chromosome have a pericentric or paracentric inversion? Why? b. Draw a sketch to show how these two chromosomes (duplicated) would pair during synapsis. Assume a CO will occur between genes E and F.

We have discussed meiosis in yeast. One ascus e one melotic event. Two haploid yeast strains are crossed together, one wild type, the other mutant for 2 linked genes. The resulting diploid strain undergoes melosis eventually (=many meiotic events > many asci). A. What will the results be if the 2 genes are very far away from each other (certainly more than 50 map units)? B. What will the results be if the two genes are right next to each other, "no distance at all, zero distance"? (Explain your answers). Results here are patterns of asci and their percentages. Like for example "50% tetratypes, 0% ditypes", etc. If you forgot what a ditype or a tetratype is, you can illustrate them like that.

In the plant, Haplopappus gracile there is one long pair and one short pair of chromosomes. In the diagrams below, anaphase of individual cells in meiosis or mitosis in a plant that is heterozygous for the genes, A and B (which are on separate chromosomes) are shown. The lines represent chromosomes or chromatids and the points of the "V" are the centromeres. For each case, indicate if the cell represents meiosis I, meiosis II, mitosis, or impossible situation. Provide a brief (one sentence) reason for your decision. 1. A A a В a B 9. A a B A a 2. а В В a A a B 9. B. a A 3.
