Homozygous spe-39 mutants were isolated from balanced heterozygous strains grown at the test temperature for at least two generations. Data shown are the means and standard deviations of 15–22 tested hermaphrodites.

  • a The percentage of embryonic lethality is shown in parentheses.

  • b These are estimates because accurate oocyte counts were not possible. The oocytes produced by these mutants did not have a well-defined shape and were not well separated from each other.
