phylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
The Pseudoautosomal Regions of the U/V Sex Chromosomes of the Brown Alga Ectocarpus Exhibit Unusual Features
The recombining regions of sex chromosomes (pseudoautosomal regions, PARs) are predicted to exhibit unusual features due to their being genetically linked to the nonrecombining, sex-determining region. This phenomenon is expected to occur in both diploid (XY, ZW) and haploid (UV) sexual systems, with slightly different consequences for UV sexual systems because of the absence of masking during ...
متن کاملSexual dimorphism and the evolution of sex-biased gene expression in the brown alga ectocarpus.
Males and females often have marked phenotypic differences, and the expression of these dissimilarities invariably involves sex differences in gene expression. Sex-biased gene expression has been well characterized in animal species, where a high proportion of the genome may be differentially regulated in males and females during development. Male-biased genes tend to evolve more rapidly than f...
متن کاملA Haploid System of Sex Determination in the Brown Alga Ectocarpus sp.
BACKGROUND A common feature of most genetic sex-determination systems studied so far is that sex is determined by nonrecombining genomic regions, which can be of various sizes depending on the species. These regions have evolved independently and repeatedly across diverse groups. A number of such sex-determining regions (SDRs) have been studied in animals, plants, and fungi, but very little is ...
متن کامل13-P010 Auxin in the control of the development of the brown alga Ectocarpus siliculosus
cate that Shh signalling controls Laminin gene expression, a critical step in the formation of the myotomal basement membrane, and that Laminin-111 has specific and essential role in myotomal basement membrane assembly. Together, our data reveal a novel role for Shh signalling in the control of basement membrane assembly and provide a framework for understanding the complex interactions between...
