Sibmating in a small, isolated population of the dioecious plant species Mercurialis ovata
1999
Holderegger, R. | Stehlik, I.
An isozyme study on the single population of the dioecious, clonal, and rhizomatous plant species Mercurialis ovata in Switzerland was carried out to determine whether small, isolated, outbred populations show low genetic variation, and whether most sexual events within such populations are sibmatings. Although the number of multilocus genotypes was very high (100%), most individuals were close relatives (mean band-sharing eveness at the 21 loci analysed = 0.91). It was thus concluded, that most breeding was indeed sibmating, but that the obligate outcrossing of M. ovata nevertheless enabled the maintenance of high clonal diversity. Some implications for conservation genetics are discussed.
