Purebred lines of fruit flies with wild type (tan) body color and stubby bristles are mated to flies with ebony bodies and normal bristles. the resulting fl offspring all have a normal wild-type body color and stubby bristles. the fl flies are crossed with flies recessive for both traits (i. e. ebony bodies and normal bristles). what phenotypes and ratios of phenotypes would you expect to find among the offspring produced by crossing the fl with flies recessive for both traits? assume you found the following results among the offspring.
wild type body, stubby bristles 430
ebony body, stubby bristles 55
wild type body, normal bristles 65
ebony body, normal bristles 450
how could you explain these results?
