Genetic Variability and Artificial Insemination
Nature, 1951IN Nature of November 11, S. L. Rabasa1 discusses the reduction in genetic variability which can take place in a population bred by artificial insemination. The problem he raises is not peculiar to populations bred in this way, but is a general one which must be faced in any population in which the parents of later generations are selected out of the ...

The Variability of Genetic Disease
New England Journal of Medicine, 2012It is never boring to be a physician because patients are so different. Each patient has a story to tell, and few have disorders that match textbook descriptions. By the same token, we need to be careful when predicting the future for our patients, and finding the appropriate therapy is often a matter of trial and error as much as science and protocol.

Genetics of Variability of CHD Risk
International Journal of Epidemiology, 1989Many genetic and environmental factors act in combination to determine inter-individual variability in risk factor traits for coronary artery disease (CAD). Geneticists have focused on the study of continuously distributed biological traits such as total plasma cholesterol.

Social Identity and Genetic Variability
Journal of Biosocial Science, 1978SummaryThe paper presents the results of five polymorphic systems in a sample of 999 individuals from Nottinghamshire. The results are classified by the socio-economic grouping of parents and self.The results show that social class differences for the genetic attributes exist and are almost linear when aggregated distances are computed.

Genetics and variability in opioid response
European Journal of Pain, 2005AbstractThe human genome project has revealed data on genomic variation which may influence the pharmacological responses. In pain therapy, the genetic background influencing the efficacy of opioid therapy is of special interest. Screening for variations in expression of drug metabolizing enzymes has been suggested as a potential tool for improving ...

Variables in the outcome of genetic counseling
Social Biology, 1976Abstract Genetic counseling is defined as a communication process which has as its goal the provision of information and support for the alleviation of human suffering. Review of the literature indicates that educational, reproductive, and psychological outcomes vary and that reproductive behavior is dependent upon stage in the life cycle, the mother's

Genetic variability in endoparasitic helminths
Parasitology Today, 1987Biochemical genetic studies have revealed high levels o f polymorphism and heterozygosity in natural populations of endoporasitic helminths. With few exceptions, these parasitic helminths appear just as genetically variable as free-living invertebrates.

Genetic variability and adaptation to stress
1997Besides an immediate cellular adaptation to stress, organisms can resist such challenges through changes in their genetic material. These changes can be due to mutation or acquisition of pre-evolved functions via horizontal transfer. In this chapter we will review evidence from bacterial genetics that suggests that the frequency of such events can ...

[Variability of cultures and genetic variability].
Annales de genetique, 1975Cultural selection is defined as a modification in gene frequency distributions within a population under the effects of socio-cultural factors. The conditions are examined which determine the efficiency of such a selection mechanism as a driving force for the evolution of the genetic pool of a social group in a state of relative isolation.

Madras Agricultural Journal, 1998
Studies on genetic variability in onion exhibited significant differences among the ecotypes for most of the characters except for shape index indicating high magnitude of variability. The estimates of phenotypic coefficient of variation were high as compared to genotypic coefficient of variation. Very high values for heritability were observed for the
