this study was carried out to investigate the genetic diversity and population structure of 90 specimens of oxynoemacheilus argyrogramma collected from sepidbarg, gamasiab and ghaleji rivers, in the west of iran. analyses using three microsatellite loci indicated that the average number of alleles in the population was 12, which was well above the reported values for freshwater fishes. the expe...

background : to determine the frequency of the single nucleotide polymorphism m287t in exon 9 of the as3mt gene in iranian population and to assess the difference in allele frequencies with other ethnicities. subjects and methods : genotyping analysis was performed on 150 healthy subjects using the pcr-rflp assay. we used chi-square analysis to check the deviation from hardy–weinberg equilibriu...

background: progesterone has been suggested to contribute to the regulation of spermatogenesis and to facilitate the production of viable sperm. investigations have showed that polymorphism of progesterone receptor (pgr) is associated with some diseases. objective: to analyze the potential relationship between male infertility and the +331g/a and progins polymorphisms of pgr gene. materials and...

We extensively analyze the maintenance of genetic variation and deviations from Hardy-Weinberg frequencies at a diallelic locus under mixed mating with apomixis and constant viability selection. Analytical proofs show that: (1) at most one polymorphic equilibrium exists, (2) polymorphism requires overdominant or underdominant selection, and (3) a simple, modified overdominance condition is suff...

The usual approach to characterizing and estimating multilocus associations in a diploid population assumes that the population is in Hardy-Weinberg equilibrium. The purpose of this study is to develop a set of summary statistics that can be used to characterize and estimate the multilocus associations in a nonequilibrium population. The concept of "zygotic associations" is first expanded to fa...

A comparative analysis of departures from multiple-locus Hardy-Weinberg equilibrium is presented for a set of four tribal Indian groups (the Yanomama, Makiritare, Wapishana and Ticuna) from the lowlands of South America. These tribes span a range of agglomeration and acculturation from the most traditional, swidden horticulturalists to frontier townspeople. The small-group social organization t...
