800x600 years ago, it was thought that a genetic component was the fundamental cause of a number retinopathy diseases including age related macular degeneration (amd). since then, information has emerged about novel genes that contribute to various forms of amd and other retinopathies that have been eluding researchers for years. in the genetic sense, only the apoe 2 and 4 genes have been found...

abstract chromosomal translocations constitute one of the most important, yet uncommon, causes of primary amenorrhea and gonadal dysgenesis. although x-autosome translocations are frequently associated with streak gonads and clinical features of the turner syndrome, the majority of x-autosome carriers may present with a variable phenotype, developmental delay, and recognizable x-linked syndrome...

Chromosome information is an important key for taxonomy, phylogeny and genetic in Trifolium plants. Thus, ten Trifolium species namely T. grandiflorum, T. resupinatum, T. dasyurum, T. campestre, T. tomentosum, T. hirtum, T. scabrum, T. lappaceum, T. stellatum, and T. repens were collected from their habitats in Fars province based on their morphologi...

Chromosome numbers of six Strobilanthes (Acanthaceae) species from China have been reported for the first time: S. compacta (2n=30), longzhouensis reptans bantonensis (2n=32), hongii (2n=32) and retusa (2n=32). Based on reports at present, x=15 x=16 are assumed to be main basic chromosome Strobilanthes.

chromosome number, meiotic behavior, and pollen viability were analyzed in 2 species of genus solenanthus, s. stamineus (desf.) wettst. and s. circinnatus ledeb, from iran. this report is the first cytogenetic analysis of these species. all taxa are diploid and possess 2n = 2x = 24 chromosome number, consistent with the proposed base number of x = 12. although this taxon displayed regular bival...

 Abstract  Background: Mosaic form of turner syndrome that represented by two or more  cell lines in an affected individual, often has limitation for detection with classical  cytogenetic methods. The present study was carried out to compare the efficiency of  interphase Fluorescence In Situ Hybridisation (FISH) and cytogenetic techniques in  detection of mosaic form of turner syndrome.  Method...
