Genetic problems

1. Pure-breeding affable flies are crossed to pure-breeding striped flies. The F 1 flies are all striped. (Both of these genes are autosomal and linked.) Which trait(s) are dominant? The F 1 females are test-crossed with the following results: affable 99 striped 101 affable striped 102 wildtype 98 What is the linkage arrangement of the F 1 flies (coupling or repulsion)? What is the phenotype of the test cross males? What is the map distance between these genes? What would be the ratio if the F 1 males were test-crossed? 2. Diagram the expected progeny in the following cross, where M represents an unknown dominant mutant: Genotype Cy M + ; D males X Cy + M + ; D + females Cy + M D + Cy + M + D + Phenotype? What would be the outcome if the above males were crossed to females homozygous for M? 3. m is a recessive unknown autosomal mutant. F 1 males of the phenotype curley and dichaete (from a cross of Cy/Pm; D/Sb X m/m) are backcrossed to m/m females. The progeny phenotypes are listed below. On which chromosome is m located? Progeny Curly Dichaete Curly "m" dichaete "m" 4. m is a recessive unknown autosomal mutant. F 1 males of the phenotype Cy D (from a cross of Cy/Pm; D/Sb X m/m) are backcrossed to m/m females. The progeny phenotypes are listed below. What chromosome is m located on? Progeny Curly Dichaete "m" Curly Dichaete Curly "m" Curly Dichaete "m" Dichaete "m" wild type
