A series of two point crosses is carried out between genes for brown eyes (bw), and arc wings (a), vestigial wings (vg) , ebony body color (e), and curved wings (cv). The following number of nonrecombinant (NR) and recombinant progeny (R) were obtained from each cross. Genes in cross Progeny (NR) Progeny (R)
