University of Oregon researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split ...

2013;13(6):601-611. In other situations, normal microarray analysis in the presence of an abnormal karyotype, such as marker chromosomes, is reassuring, as it indicates that the marker is lacking ...

The X chromosome carries at least 150 genes linked to intelligence. Since the mother has two X chromosomes to pass along while the father only has one, the mother’s contribution to the child’s ...

Choice of tests will depend on each child's clinical presentation but chromosome karyotype and fragile X DNA analysis are the only current routine recommendations. Clinical evidence of comorbid ...

The epigenetic state of chromatin, gene activity, and chromosomal positions are interrelated. A research team from the IPK Leibniz Institute (IPK) and the Karlsruhe Institute of Technology (KIT ...

The work will be of interest to scientists studying meiosis, DNA recombination, and chromosome segregation. Meiotic crossover recombination is essential for both accurate chromosome segregation and ...

For pregnant women with high risk of fetal chromosomal aneuploidy, the recommended confirmatory invasive testing options were amniocentesis and amniotic fluid chromosome karyotype analysis. For ...

This valuable study implicates a specific Wolbachia gene in driving the male-killing phenotype in a moth: This is a contribution to a growing body of literature from the authors in which they authors ...

Chromosome HRBT studies were performed on peripheral blood lymphocytes using GTG, FPG, CBG, and QFQ banding techniques. The karyotype of each patient was analysed in at least 100 metaphases. FISH was ...
