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.

Variability and Genetic Studies
1973The science of cytogenetics is concerned with the mechanisms of heredity and variability at the cellular level. The chromosomal numbers in different species, chromosomal polymorphism and the behaviour of chromosomes during the process of replication are studied because of the importance for taxonomy and evolution.
