The choice and utilisation of broodstock also represent a crucial stage in enhancement programmes, and considerations of bottleneck effects arising from reduced effective population size due to skewed parental and family contributions must be given careful consideration.
The bottleneck effects exerted by the reduction of effective population size may therefore explain the local-scale genetic differentiation and low levels of within-population genetic diversity in our studied clonal self-incompatible species, A. halleri subsp. gemmifera.
Furthermore, most populations have been estimated to experience a recent decline in the effective population size, indicating a possibility of bottleneck effects on the pattern of genetic variation.
Bottleneck effects on average heterozygosity and genetic distance with the stepwise mutation model.
We also compare autosomal and Y chromosome loci at global, and regional scales to test for Y chromosome bottleneck effects.
Mitochondrial DNA sequences from the donor (Red Sea) and the recipient regions (Mediterranean Sea were used to investigate the genetic divergence between regions and possible bottleneck effects.
In this paper, we present a behavioral kinematic wave model to explain the three bottleneck effects of sags and tunnels.
Bottleneck effects in three local populations of the fossorial rodent Ctenomys maulinus brunneus as caused by the recent eruption of the Lonquimay volcano in the Andes of Southcentral Chile are presented.
The rise of DNA evidence to the forefront of forensic science has led to high sample numbers being submitted for profiling by investigators to casework laboratories: bottleneck effects are often seen resulting in slow turnaround times and sample backlog.
Large but temporary reductions in population size due to disease, weather, or other factors also create bottleneck effects.
Bottleneck effects can be exploited by comparing the evolution of populations of different sizes (for example five, ten, 20, and 40 animals).
