Drosophila, 2 mutant phenotypes vg, e are autosomal recessive. vg trait on second

chromosome whereas e trait on third. Homozygous males vg, e, mated to homozygous

wildtype females. Males in this cross homozygous for translocation between 2nd and

3rd chromosomes. The vg and e loci included on the translocated sections of the two

chromosomes. F1 males then backcrossed to homozygous vg, e females.

Document Summary

Drosophila, 2 mutant phenotypes vg, e are autosomal recessive. vg trait on second chromosome whereas e trait on third. Homozygous males vg, e, mated to homozygous wildtype females. Males in this cross homozygous for translocation between 2nd and. The vg and e loci included on the translocated sections of the two chromosomes. F1 males then backcrossed to homozygous vg, e females. Tip for translocation questions is to make a diagram. These gametes are mated with v e female gametes. Male contains a heterozygous translocation, breakpoint on 2nd chromosome in, or very near, the vg gene. This male is mated with a female homozygous vg normal chromosome arrangement), all male offspring are vg, while all female offspring are wt. Sex linkage involved, the other chr must be x or y. This means that the chromosome involved in the translocation are the second chromosome and: x chromosome.

Hint: To calculate the distance between two points, you can use a method defined in the appendix in the Maputilities class . Write a method findNearest Station which takes as input a double x and a double y ad the Metrostation which is nearest to the x and y. To do this, it should leather all the Metrostations of all the Metrotines inside of this lines and find the Metro Station that is the smallest distance away. You can use the same appendix method as in the precis i on You may assume that there is a leadine MetroLine defined in the property lines. You may also assume that every MetroLine in lines has at least one Metrostation in Hint There is no method such as getAll Station defined a Metrotine ohjeet. This is since providing this method would rewal a lot about the implementation of the Metrolines and would differ depending on the kind of collectice you are using to store it. However, you can simulate this art of method by using the get PirstStop () and get Next Stop () methods to access every entry of the AmyList. Remember the condition that will cause getNext Stop (to be null • A method qet Neighboringstations which takes input a Metrostation station and re- turns an ArrayList The Arrayut Metrostation whild consist of all nephring stations to station possibly many if the station in ce may lines).
