A single uniparentally
(maternally) inherited marker does not provide enough resolution to detect N.
Effective sizes and dynamics of uniparentally
and biparentally inherited genes.
Ancient marine hunter-gatherers from Patagonia and Tierra del Fuego: Diversity and differentiation using uniparentally
inherited genetic markers.
Molecular studies--especially those focused on the uniparentally
inherited mitochondrial DNA (mtDNA)-continued to have an impact on anthropological studies in general (Cann, et al.
1975), recent theory and experiments indicate that uniparentally
inherited haploid markers (e.g., mtDNA; see Wade et al.
By contrasting the distribution of these uniparentally
inherited cytoplasmic markers with biparentally inherited nuclear markers, estimates of the relative contribution of pollen dispersal, seed dispersal, and the breeding system to patterns of genetic variation can be obtained (Ennos 1994, McCauley 1994).
If the disappearing chromosome originally came from the parent who contributed only one, then the child may harbor cells that are uniparentally
However, geographic sampling in the Southern Ocean has previously been limited primarily to the Antarctic Peninsula, and genetic analyses relied solely on mtDNA, which is uniparentally
inherited and not suitable for exploring potential admixture.
The availability of uniparentally
inherited organellar DNA markers has opened a new avenue for exploring patterns of gene flow via seed and pollen (McCauley 1994).
Mitochondrial DNA cannot be used to identify [F.sub.1] hybrids because it is uniparentally
inherited, and morphology is unreliable because [F.sub.1]s may fall into parental clusters (Neff and Smith 1978; Ross and Cavender 1981; Lamb and Avise 1987).
This substitution results from the fact that the chloroplast is uniparentally
inherited and therefore, behaves as a haploid marker.
