Examples
-
A very different result emerges if one assumes that groups of organisms such as demes, kin-groups, or species, though not individuals, are nevertheless subject to selection.
Darwinism Lennox, James 2004
-
He constructed a model with populations subdivided into numerous, semi-isolated subpopulations, or demes, in which spontaneous chromosome rearrangements with heterozygote disadvantage occur.
-
Hedrick and Levin 1984 suggested a mechanism that greatly increases the probability of fixation for negatively heterotic chromosome rearrangements during migration and colonization of other demes.
-
In addition, the model included random extinction and colonization of demes.
-
For this process, the fixation rate in a species composed of many semi-isolated demes is approximately equal to the rate of establishment of new gene arrangements in a single one of its demes.
-
If the group joins another existing group, given that most demes are small, the newcomers may compose a significant percentage of the combined deme.
