Reiteration Frequency of Haemoglobin Genes in the Duck

Nature New Biology, 1972
Hybridization between duck DNA and duck haemoglobin mRNA shows that there is little or no reiteration of the haemoglobin ...

The effects of random selection on gene frequency [PDF]

Mathematical Biosciences, 1976
The equations satisfied by the gene frequency for various cases of dominance are converted to the type of stochastic differential equation associated with a diffusion process. Using the physical approach to stochastic integrals, the solutions of the corresponding Fokker-Planck equations are obtained.

GENE FREQUENCY CLINES IN EUROPE: DEMIC DIFFUSION OR NATURAL SELECTION?

, 1996
According to the demic diffusion model ofCavalli-Sforza and colleagues, agriculture was spread through Europe by a rapid population expansion of early farmers from the Near East.

Geographic Variation in Human Gene Frequencies

1983
A major reference for the analysis of geographic variation in human gene frequencies is the tabulation compiled by Mourant et al. (1976). It provided also the stimulus for developing quantitative methods of displaying and testing gene frequency distributions (Piazza et al. 1981a).

Bayesian estimation and testing of gene frequencies

Theoretical and Applied Genetics, 1995
This article explains estimation of gene frequencies from a Bayesian viewpoint using prior information. How to obtain Bayes estimators and the highest posterior density credible sets (Bayesian counterpart to classical confidence intervals) for gene frequencies is described. Tests of hypotheses are also discussed.

On the Effects of Genetic Counselling on Gene Frequencies

Human Heredity, 1970
It has been suggested that genetic counselling and therapeutic abortion can lead to increases in the frequencies of autosomal genes determining recessive diseases.

Mutant gene frequencies in cats of Cyprus

Theoretical and Applied Genetics, 1972
Three areas of the island of Cyprus have been sampled for frequency of nine mutant genes among the domestic cat population. The significance of the observed frequencies are discussed with particular reference to the existence of world-wide clines for O (orange) and t (b) (blotched tabby).

Changing Gene Frequencies in Populations

1983
Recurrent selection populations (RSP’s) have been effectively utilized for changing gene frequencies in populations of various crop plants and for pyramiding genes for resistance to specific plant diseases. The method has been particularly adapted for cross-pollinated crops and has been especially successful in developing disease resistance in maize ...

Equilibrium frequencies of α-globin genes

Journal of Theoretical Biology, 1983
A mathematical model has been developed to study the mechanism of the maintenance of variable numbers of alpha-globin genes in human populations. The model incorporates both selection and unequal crossing-over. The selection is formulated so that a homozygous individual with a double deletion is lethal and a heterozygous individual with a deletion or ...
