On the Effects of Genetic Counselling on Gene Frequencies
Human Heredity, 1970It 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, 1972Three 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
1983Recurrent 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, 1983A 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 ...

The «Accuracy» of estimates of MNS gene frequences
Acta geneticae medicae et gemellologiae, 1956SummaryWiener's methods for estimating gene frequencies from MNS data are compared with the maximum likelihood methods, and found not to be fully efficient. The extra effort and expense which would result from the use of such methods is discussed. It is concluded also that the number of significant figures advised by Wiener is not sufficient.
