ARE ENZYME LOCI SELECTIVELY NEUTRAL IN HAPLOID POPULATIONS OF NONVASCULAR PLANTS?
1Department of Natural History, The Museum, Norwegian University of Science and Technology, N-7491, Trondheim, Norway.
Abstract:
Enzyme data from 12 previously published studies of haploid bryophyte populations were subjected to tests of selective neutrality and population equilibrium. Altogether 280 samples were tested using the Ewens-Watterson test, the Ewens exact test, and Chakraborty's test. The Ewens-Watterson and the Ewens exact tests revealed neutrality in 84.6% of the cases, whereas the Chakraborty test revealed neutrality in 100% of the cases. Neutrality may thus explain the relatively high amounts of genetic variation found in these organisms. Possible hidden population sub-structuring and nonrandom field sampling of genotypes in many of the studies could make Chakraborty's test more reliable than the two others.
