  1. Given: A testcross between a (+++)/(ymw) female fruit fly and a ymw/Y male yields the following:

         

                              Gametes                                  Numbers                                                                                 (+++)                                   3,501

                              (ymw)                                     3,471               

                              (++m)                                      1,754

                              (yw+)                                      1,700               

                              (y++)                                       28

                              (+mw)                                     32                    

                              (+w+)                                      6

                              (y+m)                                      3                      

                                                                        Tot. = 10,495                        

a. What is the configuration of the heterozygous parent?

b. Which gene (y, m or w) is in the middle?

c. Determine the interference (I). Is the interference + or -? Explain.

A female fruit fly with singed bristles was mated with a male from a true-breeding wild-type stock with long bristles. All of the F1 females had wild-type long bristles and all of the F1 males had singed bristles. If the F1 flies are intercrossed, the expected ratio of long to singed bristles in the F2 flies is Multiple Choice 3:1 in both sexes. 3:1 in females, while all the males will have singed bristles. 1:1 in both sexes. 1:1 in...

In the fruit fly, Drosophila melanogaster, a spineless (sp, no wing bristles) female fly is mated to a male that is claret (cl, dark eyes) and hairless (h, no thoracic bristles). Phenotypically wild type F1 female progeny were mated to fully homozygous (mutant) males and the following progeny (1000 total) were observed.             PHENOTYPES                    NUMBER OBSERVED             spineless                                             316             wild                                                         8             claret, spineless                                  136             claret                                                     37             claret, hairless                                    304             hairless, claret, spineless                     12             hairless                                               144             hairless, spineless                                43 What is the correct gene map for these genes?...

A female fruit fly with the recessive mutant phenotype of white eyes and miniature wings is mated with a male possessing the wild-type phenotype of red eyes and normal wings. Among the F1s, all the females are wild-type while all the males exhibit the mutant phenotype. The F2s resulting from a test cross exhibit predominantly (63%) parental phenotypes. How do you explain these results?

Probability Theory. In a given population of two-earner male-female couples, male earnings have a mean of $50,000 per year and a standard deviation of $15,000. Female earnings have a mean of $48,000 per year and a standard deviation of $13,000. The correlation between male and female earnings for a couple is 0.90. Let C denote the combined earnings for a randomly selected couple. c. What is the standard deviation of C?
