Heterozygote Advantage for Fecundity
Heterozygote advantage, or overdominance, remains a popular and persuasive explanation for the maintenance of genetic variation in natural populations in the face of selection. However, despite being first proposed more than 80 years ago, there remain few examples that fit the criteria for heterozygote advantage, all of which are associated with disease resistance and are maintained only in the...
متن کاملcohesion and cohesive devices in a contrastive analysis between ge and esp texts
the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...
15 صفحه اولConflict on the sex chromosomes: cause, effect, and complexity.
Intralocus sexual conflict and intragenomic conflict both affect sex chromosome evolution and can in extreme cases even cause the complete turnover of sex chromosomes. Additionally, established sex chromosomes often become the focus of heightened conflict. This creates a tangled relationship between sex chromosomes and conflict with respect to cause and effect. To further complicate matters, se...

مطالعه حاضر با هدف بررسی وجود رابطه ی ممکن میان هوشهای زبانی و منطقی زبان آموزان انگلیسی و تعداد و انواع مغلطه های زبانی و شواهد در متنهای استدلالی آنان انجام پذیرفته است.بدین منظور، 70 زبان آموز با سطح زبانی متوسط به بالا از دو موسسه زبان انگلیسی در ایران انتخاب شده و پرسشنامه های مزبوطه را تکمیل نموده و متنی استدلالی نوشتند. متون نوشته شده مورد بررسی قرار گرفته و نمرات پرسشنامه ها محاسبه شده ...
15 صفحه اولMolecular basis of sex determination in haplodiploids.
Sex in many species of Hymenoptera (ants, bees and wasps) is determined by a single locus that is heterozygous in females and hemizygous in (haploid) males. Beye and colleagues have now cloned the csd locus in the honeybee Apis mellifera and provide functional evidence that this gene is the primary switch in the sex-determination cascade of honeybees and possibly all Hymenoptera.
