I. Results of experiment with banana and fishmeal
| Days of selection | 1 | 2 | 3 | 4 | 5 | 6 | 7 | |
|---|---|---|---|---|---|---|---|---|
| No. of eggs correctly laid in banana | 0 | 6 | 0 | 5 | 57 | 21 | 0 | |
| No. of eggs correctly laid in fishmeal | 47 | 85 | 75 | 69 | 53 | 12 | 30 | Parents |
| No. of eggs correctly laid in banana | 0 | 0 | * | |||||
| No. of eggs correctly laid in fishmeal | 75 | 42 | Generation 1 |
* At this point no egg numbers were counted for three days although phials were maintained. No eggs were laid correctly on banana during this period.
