a
Genome sizes were calculated by using three EcoRI restriction profiles. The values are means ± standard deviations.
b
The values are medians ± 95% confidence intervals around the medians, as calculated by the method of Velleman and Hoaglin (21); the data obtained enabled a pairwise statistical comparison of the group medians to be made at the 95% confidence level.
c
The numbers in parentheses are numbers of replicates.
