a Forty uninucleoid and 40 binucleoid cells of each size group were examined. Binucleoid total DNA is the mean sum of DNA content of large and small binucleoid cells. The L/S ratio is the ratio of DNA content of large binucleoid cells/DNA content of small binucleoid cells. The Bi.total/uni. ratio is the ratio of binucleoid total DNA/uninucleoid cell DNA content. Values are means (standard errors). DNA content is given in arbitrary units. 

b Differences between means of small and large nucleoids were significant at <0.001 level for all size groups (paired-sample t test). 

c Ratios were not significantly different from 1.0; chi-square test, χ20.05[39] = 54.6 (for L/S ratios) or χ20.05[3] = 7.8 (for Bi.total/uni.ratios).
