  • Differences between wild-type groups in each time period were not significantly different from each other, except in cases indicated by **, where differences were seen between devitellinized embryos or P1 isolates compared to intact embryos. No significant differences were seen between devitellinized embryos and P1 isolates.

    n, number of cases; NA, not applicable.

  • * The time period between P4 birth and MSxx birth.

  • The time of MSxx birth until MSxx division. For the range of numbers, see Fig. 3B and Fig. 4G,H.
