| Date | Late 19th to early 20th century |
| Extent | 1 slide |
| Description | Slide shows 'arrangement of parts of the second (white) and third (stippled) chromosomes in Drosophila melanogaster and D. artificialis.' Drosophila = fruit fly.
At the top of the image there are two sets of chromosomes for both types of fly; the D. melanogaster produces two 'v' shaped gametes (sex-cells) one white, labelled 'a b c' and one shaded, labelled 'd e f'.
D. artificialis produces four possible sets of gametes all with the 'a b c' and 'd e f' labels; set (1) is 'a e a' with the 'e' shaded and 'd b c' with the 'd' shaded.
Set (2) is as set one, but the second gamete is 'f b c' with 'f' shaded.
Set (3) is 'd e f' shaded and 'd b c' with 'd' shaded
Set (4) is 'd e f'' shaded and 'f b c' with 'f' shaded.
