  • * The numbers shown here are ectopic sex comb teeth per leg. They are derived by dividing the total numbers of sex comb teeth in second and third legs of male progeny by the total numbers of legs examined. The paternal genotypes and numbers of legs examined are shown in parentheses. The degree of leg transformations appears to be significantly higher when the maternal genome carries Hdac1 mutation, suggesting a maternal effect of Hdac1. The weak effect of Hdac1def8 might be related to perdurance of maternal products (data not shown). Hdac1 heterozygotes do not have ectopic sex comb teeth.
