A Study of the Tâleqâni's Osul-e Dastur-e Zabân-e Fârsi
The purpose of the present paper is to make a linguistic analysis of Tâleqâni's Osul-e Dastur-e Zabân-e Fârsi which is one of the typical Persian Grammars written on the traditional model. I also intend to criticize some of his grammatical description and his own view of Persian language and grammar in general.Tâleqâni, together with other traditional grammarians, classifies the parts of speech into nine, i. e. nouns, adjectives, verbs, pronouns,…
The Sociobiology of Sex and Sexes Today [and Comments and Reply]
Three problems pertaining to sex and sexes-why sex exists at all, why there should normally be two mating types in a sexual species, and why the two should so often be dimorphic (take the form of male and female)-have created a crisis in evolutionary theory. This paper contains a sketch of these puzzles and some opinions about the direction in which solutions are likely to be found, including a new theory of sex chromosome morphology and activity…
Social selection and evolution of human diseases
Disease incidences in human populations depend on etiology of the disease, the fitness of individuals, and demographic changes of the population. The fitness of an individual is determined not only by the disease but also by other factors such as cultural and social reaction to the disorder and demographic changes of the population. Social selection studies the effect of the social behavior on the incidence of a trait. In studies of Huntington's …
Social selection in human populations: Deterministic analyses on the modification of the fitness of offspring by affected parents
A social selection model for deleterious genes has been studied by considering two alleles at one locus. The model allows for the fitness of an individual to be determined by parental phenotypes as well as by his/her own phenotype. We show that the equilibrium gene frequency depends on the loss of fitness of an individual due to the trait (γ) and due to affected parents (P), and the probability that the heterozygote develops the trait (h). We sho…
Cultural inheritance of the desire for male offspring and the incidence of a sex-linked lethal disease
This paper studies the effect of having at least one male offspring on a sex‐linked recessive disease and the fraction of affected males due to fresh mutations. The equilibrium frequency of heterozygous females depends not only on the intensity of the reproductive compensation, but also on the time of mutational change. It has been shown that the frequency ranges from 4u without reproductive compensation to √2u or √3u with strict compensation, wh…
The effect of variable progeny size and social selection on the population dynamics of rare lethal genes
When a family has a member affected by a rare lethal genetic disease, the normal members of the family have a reduced chance of marrying or of reaching the fertility level of the general population. This paper shows that gene frequency change is divided approximately into two parts: the change due to individual selection and that due to social pressure. It is also shown that a large progeny size in a family generally decreases the equilibrium of …
The effect of social selection due to familial mental retardation on the marriage frequency of normal individuals
This paper compares the marriage frequencies of normal individuals with or without mental retardates in their nuclear families for the different combinations of sex and parental and sib phenotypes. Multivariate analysis indicates that there is a difference in the marriage frequencies of normal individuals with and without retarded family members caused by social response to the trait. This response differs according to the sex of the normal indiv…
