Solved by a verified expert:1. Pure-breeding affable flies are crossed to pure-breeding striped flies. The F1 flies are allstriped. (Both of these genes are autosomal and linked.)Which trait(s) are dominant?The F1 females are test-crossed with the following results:affable 99striped 101affable striped 102wildtype 98What is the linkage arrangement of the F1 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 F1 males were test-crossed?2. Diagram the expected progeny in the following cross, where M represents an unknowndominant mutant:Genotype Cy M+ ; D males X Cy+ M+ ; D+ femalesCy+ M D+Cy+ M+ D+Phenotype?What would be the outcome if the above males were crossed to females homozygous forM?3. m is a recessive unknown autosomal mutant. F1 males of the phenotype curley anddichaete (from a cross of Cy/Pm; D/Sb X m/m) are backcrossed to m/m females. Theprogeny phenotypes are listed below.
