the study of cognition and attitudes toward family life and sex, particularly among the young population, is one of the important areas of health behavior. this study attempts to find the degree of knowledge and attitudes of the female students of teheran university. the findings reveal that although the girls under the study expressed some attitudes towards family life not common in the tradit...

The interest in the effect of genotype × environment interaction is increasing because animal breeding programs have become geographically broader. Climate changes in the next decades are also expected to challenge the present breeding goals, increasing the importance of environmental sensitivity. The aim of this work was to analyze genotype × environment interaction effect on cattle BW using t...

Several variables have been reported to affect the expression of sex differences in the analgesic potency of morphine. Although the effect of genetic background on morphine analgesia has been well documented, the relevance of genotype to sex differences in morphine analgesia has rarely been considered. The present study investigated morphine dose-response relationships in male and female mice o...

background : apolipoprotein e (apoe) gene encodes an important protein in reforming injuries of central nervous system (cns). it is assumed that various apoe alleles may be functionally different. the purpose of this study was to investigate the distribution of apoe genotypes in multiple sclerosis (ms) patients in a small cohort of iranians. methods : in this case-control study, blood samples o...

Pati K., A. Das Munshi and T. Kanti Behera (2015): Inheritance of gynoecism in cucumber (Cucumis sativus L.) using genotype gbs-1 as gynoecious parentGenetika, Vol 47, No. 1, 349-356. The inheritance pattern of gynoecious sex expression in cucumber was studied by utilizing a gynoecious line (GBS-1) and two monoecious lines (Pusa Uday and Punjab Naveen). Crosses were made between gynoecious line...

Sex in Oreochromis niloticus (Nile tilapia) is principally determined by an XX/XY locus but other genetic and environmental factors also influence sex ratio. Restriction Associated DNA (RAD) sequencing was used in two families derived from crossing XY males with females from an isogenic clonal line, in order to identify Single Nucleotide Polymorphisms (SNPs) and map the sex-determining region(s...

Owing to the demand for sustainable sex-control protocols in aquaculture, research in tilapia sex determination is gaining momentum. The mutual influence of environmental and genetic factors hampers disentangling the complex sex determination mechanism in Nile tilapia (Oreochromis niloticus). Previous linkage analyses have demonstrated quantitative trait loci for the phenotypic sex on linkage g...
