bottleneck effect

The cell metabolism could not be regulated, creating bottleneck effects or the production of unnecessary proteins.

Phenomenon like genetic drift, foundation and bottleneck effects cause large errors, particularly in haplogroup studies.

These statistics can be accounted for by inbreeding and two related concepts, the bottleneck effect and genetic drift.

Gates were often placed at tight corners, forcing a bottleneck effect upon the invading force, or even simply at right angles within a square courtyard.

This form might be separable as a distinct species, or it might just be a particularly distinct population due to genetic bottleneck effects.

With lower contact levels between sexes, there may likely be reduced fitness due to inbreeding and less genetic variability in the gene pool, following the bottleneck effect.

Under the single-channel architecture, any CPU with a bus speed greater than the memory speed would be susceptible to this bottleneck effect.

But mitochondrial DNA is prone to rapid sequence changes as well as founder and bottleneck effects, which could exaggerate the divergence.

Conservation genetics of the alligator snapping turtle: cytonuclear evidence of range-wide bottleneck effects and unusually pronounced geographic structure.

Though this particular species of microhylid's experienced a severe population bottleneck effect in the past, its succeeding expansion has allowed its current population trend to remain stable.

For example the bottleneck effect; when natural disasters dramatically reduce the size of a population resulting in a small population that may or may not fairly represent the original population.

In 1975, he and collaborators presented a mathematical formulation of population bottleneck effects and clarified the genetic meaning of bottleneck effects.

Ragsdale et al. (2004) proposed that movement from soybean to buckthorn may produce a bottleneck effect that inhibits the ability of soybean aphids to overwinter in great numbers.

What may make the bottleneck effect a sampling error is that certain alleles, due to natural disaster, are more common while others may disappear completely, making it a potential sampling error.

The stable intracellular conditions as well as the bottleneck effect experienced during the transmission of a few bacteria from the mother to each nymph increase the probability of transmission of mutations and gene deletions.

The bottleneck effect is a double-edged sword for species that live a long time because the loss of genetic diversity would not be as obvious or as severe, but once it occurred, it would be harder to recover.

Platyctenida are considered to be a phylogenetically young group along with the orders Lobata and Beroida and are believed to have stemmed from an ancestral version of the order Cydippida, after some kind of bottleneck effect in the phylum.
