glacial refugia) through founder effects
and bottlenecks as a result of multiple stepwise colonization events (Hewitt, 1996; Widmer and Lexer, 2001; Jim6nez et al.
You can end up with limited mating groups that have nothing to do with religion that have founder effects
Future research also could be directed toward founder effects
beyond the kind of malfeasance considered here.
1] may be reporting the true frequency (if Finland avoided the founder effect
of this mutation in Europe), all samples that tested as normal should have been confirmed by an alternative DNA assay to rule out the occurrence of false-negative results.
Interestingly, with respect to neurodegenerative disease, there is some evidence for a founder effect
for Huntingtons disease in SA, possibly arising from an early Dutch settler, since there is a common haplotype indicative of a European origin.
So does such a founder effect
play a similarly significant effect in the dispersal and differentiation of languages?
A founder effect
is a term from biology that refers to when a small group breaks off from a larger group.
3,4] A founder effect
results when a small subset of a large population establishes a new population.
However, she explains, amongst these, no founder effect
mutation was found, i.
For both ENG and ACVRL1, many mutations have been reported by independent groups in different countries, in most cases without any evidence of a founder effect
, which could be suspected only in a limited number of cases.
It was postulated at the time that this increased incidence could be attributed to a founder effect
Evidence from our research laboratory suggests that this SA SCA7 haplotype may be present in a SCA7 family native to northern Namibia, and a Zambian SCA7 patient, supporting the hypothesis that the founder effect
may extend geographically into areas north of SA.
