A homozygous wild-type fly was mated with a cherub, black, and cinnabar fly, andd the resultinf F1 females were test-crossed with cherub, black, and cinnabar males. The following progeny were produced from the testcross:

ch b cn 753
ch+ b+ cn+ 750
ch b+ cn 105
ch+ b cn+ 102
ch+ b cn 40
ch b+ cn+ 41
ch+ b+ cn 4
ch b cn+ 5
