Light eyes (It), dumpy wings (dy) and black body (b) are all at loci on chromosome 2 in Drosophila melanogaster. Light eyes and dumpy wing loci are separated by 20 map units. Black body is 15 map units from dumpy wings. The order of the loci is light eyes - dumpy wings -- black body. A dumpy winged, black body male is crossed to a female with light eyes. The F1 is wild-type. F1 females are test-crossed (to a It, dy, b male) to produce 1000 progeny. Assume a coefficient of coincidence of 0.7. How many light-eyed flies (not dumpy wing, not black body) are expected from this test cross
