Academics

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

Genes in cross	Progeny (NR)	Progeny (R)
a, bw	2224	117
a, cv	2609	823
a, e	3200	3200
a, vg	5172	2379
bw, cv	4614	1706
bw, e	4150	4150
bw, vg	2796	1434
cv, e	3116	3116
cv, vg	2102	305
vg, e	4559	4559

Using these data from two-point crosses, create a genetic map for these genes, providing the order of the genes and the best estimates of the distances separating them.
