QUESTION 18 Which of the following statements about Transmission Ratio Distortion, as exemplified by the SD (Segregation Distorter) system in Drosophila, is TRUE? Transmission ratio distortion is caused by inversions on the SD chromosome. O The SD system includes a cis-acting, shortened version of a RanGAP protein and a trans-acting DNA repeat locus. O Distortion operates only in males, due to sex-linkage. The SD chromosome distorts transmission ratios by killing gametes that do not contain it. The loci that make up the SD system assort independently of each other at meiosis.

Question 15: Consider the consequence if one of the mutations you tested for complementation was a dominant mutation. You should see that complementation tests could not be used to provide information about dominant mutations. a) If a mutation were dominant how would your interpretation of the phenotype of the diploid be altered? No change would occur wit b) How would you test whether any of these trp mutations were dominant? There is no way to test for

The chromosome 9/22 translocation associated withCML (chronic myelogenous leukemia) is called thePhiladelphia chromosome after the city in which itscancer association was first discovered in 1960.People with CML do not inherit this translocation—it occurs in somatic cells. Why do you think that thisparticular translocation that fuses the bcr and ablgenes happens independently in the somatic cellsof many different people?
The Drosophila gene Sex lethal (Sxl) is deserving of itsname. Certain alleles have no effect on XY animals butcause XX animals to die early in development. Other alleles have no effect on XX animals but cause XY animals to die early in development. Thus, some Sxl allelesare lethal to females, while others are lethal to males.a. Would you expect a null mutation in Sxl to causelethality in males or in females? b. Why do Sxl alleles of either type cause lethality ina specific sex?The gene transformer (tra) gets its name from sexualtransformation, as some tra alleles can change XXanimals into morphological males, while other traalleles can change XY animals into morphologicalfemales.c. Which of these sex transformations would becaused by null alleles of tra and which would becaused by constitutively active alleles of tra?d. In contrast with Sxl, null tra mutations do notcause lethality either in XX or in XY animals.However, the Sxl protein regulates the productionof the Tra protein. Why…
8.18 Irradiatioh of Drosophila sperm produces transloca- tions between the X chromosome and autosomes, between the Y chromosome and autosomes, and between different autosomes. Translotations between the X and Y chromosomes are not produced. Explain the absence of X-Y translocations. The birth of this child prompted the Dentons' physician to order a chromosome study of parents and child. The results of the study are shown in the accompanying fig- ure. Chromosome banding was done, and all chromo- somes were normal in these individuals, except some copies of number 6 and number 12. The number-6 and number-12 chromosomes of mother, father, and child are shown in the figure (the number 6 chromosomes are the larger pair): Child Mrs. Denton Mr. Denton a. Does either parent have an abnormal karyotype? If so, which parent has it, and what is the nature of the abnormality? b. How did the child's karyotype arise? (What pairing and segregation events took place in the parents?) e. Why is the child…

A Drosophila male is heterozygous for a reciprocaltranslocation between an autosome and the Y chromosome. The part of the autosome now present onthe Y chromosome contains the dominant mutationLyra (shortened wings); the other (normal) copyof the same autosome is Lyra+. This male is nowmated with a true-breeding, wild-type female. Whatkinds of progeny would be obtained, and in whatproportions?
