Maintaining the Diversity of Genetic Programs
2002The loss of genetic diversity in evolutionary algorithms may lead to suboptimal solutions. Many techniques have been developed for maintaining diversity in genetic algorithms, but few investigations have been done for genetic programs. We define here a diversity measure for genetic programs based on our metric for genetic trees [3].

This project examined the effects on genetic diversity of oysters by hatchery techniques and selective breeding. The edible oyster industry in Australia comprises of two main species: Crassostrea gigas and Saccostrea glomerata, which are produced by hatcheries or natural spatfall, respectively.

Genetic diversity in the Caucasus.
Human biology, 1994We report genetic variation in the Caucasus, a region showing extreme linguistic differentiation. Spatial autocorrelation analysis of 31 alleles in 793 samples and maps of interpolated allele frequencies show significant geographic structure, but the patterns are clinical for only a few alleles. Many gene frequency distributions are patchy, most likely

Pediatrics, 1977
Only about 7% of all human genetic diversity is between major races. It would appear then that the superficial characters of skin color, hair form, lip, nose, and eye shape that we use to distinguish human races are atypical and do not represent the mode of human genetic variation.

An Anthropocene map of genetic diversity
Science, 2016The Anthropocene is witnessing a loss of biodiversity, with well-documented declines in the diversity of ecosystems and species. For intraspecific genetic diversity, however, we lack even basic knowledge on its global distribution. We georeferenced 92,801 mitochondrial sequences for >4500 species of terrestrial mammals and amphibians, and found that

Genetic Diversity in Mycobacterium tuberculosis
2013Recent years have witnessed an increased appreciation of the extent and relevance of strain-to-strain variation in Mycobacterium tuberculosis. This paradigm shift can largely be attributed to an improved understanding of the global population structure of this organism, and to the realisation that the various members of the M.

Diversity of Regulation of Genetic Transcription
Nature New Biology, 1972Functional coupling of the translational machinery to transcription is obligatory for the transcription of some genes, including the trp operon, but not for others.

Genetic diversity of Rhodopirellula strains
Antonie van Leeuwenhoek, 2013Rhodopirellula baltica SH1(T) is a marine planctomycete with 7,325 genes in its genome. Ten strains of the genus Rhodopirellula were studied in whole genome microarray experiments to assess the extent of their genetic relatedness to R. baltica SH1(T). DNA of strains which were previously affiliated with the species R.

The Ecology and Genetics of Microbial Diversity
Annual Review of Microbiology, 2004▪ Abstract Natural communities of microbes are often diverse, a fact that is difficult to reconcile with the action of natural selection in simple, uniform environments. We suggest that this apparent paradox may be resolved by considering the origin and fate of diversity in an explicitly ecological context. Here, we review insights into the ecological
