The offspring of two heterozygous gray-bodied, normal-winged flies should be 50% graybodied/

normal wings (BbRr) and 50% black-bodied/vestigial wings (bbrr) because these alleles are linked. If a small number, say 15%, of the offspring are instead black-bodied with normal wings, this is most likely the result of: a. crossing-over. b. incomplete dominance. c. codominance. d. an error in meiosis. e. mutation.
