Females carrying mutations for histone variants or chaperones were crossed to Pc4 males. The numbers of extra sex comb teeth (ESCT) on both L2 and L3 of their progenies were scored. The averages and standard error of the mean (SEM) of ESCT per leg are shown. Total numbers of legs examined are indicated in parentheses. See S5 Fig for the range of % ESCT. Note that none of these histone chaperone or variant mutants show ESCT phenotype alone. Bal, Balancer.
