This set of genes also has an important evolutionary role in guiding people to find mates who are genetically dissimilar, because genetic diversity within their offspring's MHC will lead to an increased chance of surviving novel diseases and environments.
Because chimeras harbour a greater genetic diversity than genetically homogeneous individuals, they can display "chimeric vigour", i.e., they may be able to use or cope with a wider range of environmental conditions.
These colonies harbour high levels of genetic diversity, are genetically differentiated from each other and exhibit a pattern of genetic isolation by distance [ 19].
Even a species that survives extinction can lose much of its genetic diversity as local, genetically distinct populations are lost from most of the species' original range.
Notably, some nearby spawning populations were very genetically distinctive, with high genetic diversity and high proportions of private alleles, as characterized by the Belle Isle restoration site in the Detroit River.
Alternatively, the division of labor hypothesis suggests that colonies with greater genetic diversity have greater genetically determined behavioral diversity or broader task performance thresholds, which allows for a more efficient division of labor or the exploitation of rare genetic specialists [ 6, 13- 16].
The species has limited genetic diversity, although three genetically distinct geographically defined subpopulations have been described (Jones et al., 2004; Miller et al., 2011).
Hence, to test whether the Tabasco flood led to homogenization of locally adapted populations, we compared patterns of genetic differentiation, genetic diversity, and especially genetically detectible individual dislocation before and after the flood.
Dogs appeared to be the most genetically diverse when the diversity of the five different canid groups was estimated using all 61,435 SNPs from the canine microarray.
