The upper half of the graph indicates the eggs laid per female per day and the lower half shows the percentage of eggs to hatch for each day of the test period. Circles in the left graph represent mean values for 40 females and 50 males in 5 cultures, circles in the center graph are for 120 females mated to 120 males in 12 cultures, and circles in the right graph are for 96 females mated to 120 males in 12 cultures.

Adults raised on a carnitine-supplemented diet were fed a diet containing X 10~* M choline for 15 days. The number of eggs laid per female and the percentage of these eggs to hatch was determined for each day during the test period (Fig. 1). Almost none of the eggs hatched FIGURE 1.
