Population genetics and natural selection

Genetica, 1957
Genotypic differences are the raw material on which selection acts but not all kinds of genotypic differences are of equal importance in this connection. FISHER (1930) showed that whether or not mating occurs at random, the population genotypic variance for any quantitative character may be analyzed into a number of components and that one of these ...

Genetic Selection and Equilibrium Stability

Acta geneticae medicae et gemellologiae, 1977
The problem of the equilibrium stability of a phenotypic selection process, with a single pair of autosomal alleles, has been numerically studied, on the basis of previously established reproduction differential equations.

GENETIC SELECTION AND THE STATUS OF THE EMBRYO

Bioethics, 1993
In this paper I want to try to clarify the nature of the two different problems indicated in the title: there is a lively debate on whether or not genetic selection is a morally licit practice, and there are strong disagreements on whether or not the embryo is a person.

Genetic selection in farmed deer

Veterinary Record, 1991
Selection is the major tool used by breeders to improve the genetic quality of their livestock. Traditional methods of selection are well proven and useful in improving the economic merit of livestock. The performance of an animal is affected by its genetic quality and by the environment in which it is reared.

Selected features of marsupial genetics

Genetica, 1993
As a consequence of the ancient separation of the marsupial and eutherian lineages, comparative genetical studies of these two mammalian taxa can be particularly informative. The potential for marsupial genetical research has been enhanced by the development of laboratory colonies of three 'model' species--Macropus eugenii, Monodelphis domestica and ...

Selection Analysis in Genetic Algorithms

1998
This paper describes a formal framework for the analysis of genetic algorithms. The model is based on the idea that over the space of populations an equivalence relation can be defined, as well as a metric on the space of equivalence classes induced by this relation.
