Abstract | Genome size variation in the common frog (Rana temporaria) was investigated with flow cytometry in three latitudinally separated populations in Sweden to see whether it could provide a useful tool for sex-identification in this species. Depending on the sex and population, per cell DNA content (2C value) varied from 8.823 to 11.266 pg with a mean (± SE) 2C value of 9.9619±0.083 pg. Analysis of variance revealed significant differences in genome size among populations and between sexes. Females had ca 3% larger genomes (x=10.133±0.068 pg) than males (x=9.832±0.068 pg) in all of the populations (sex × population interaction: P>0.10). Individuals from the southernmost population had significantly (x=9.330±0.081 pg) smaller genomes than those from the more northern populations (x=10.032±0.085 and x=10.584±0.085 pg, respectively). These results are in line with the interpretation that males in the common frog are the heterogametic sex, and that there exists large (up to 12%) geographic variation in genome size in this species. However, the sex differences in the genome size are too small to be useful in individual sex identification. |
