Calculating genotypes

 A black body color (as opposed to the wild-type yellow color) in fruit flies is due to the recessive ebony allele, e. Small wings are due to the recessive vestigal allele, vg.  You wish to deduce the genotype of a yellow-bodied large-winged male fruit fly.  What are all the possible genotypes this male could be at the ebony and vestigal loci?  What is the genotype and phenotype of the female fruit fly you should use in a testcross?   What are the phenotypic ratios expected from this testcross for each of the possible male genotypes?
