Information on the sex chromosome content of sperm has been obtained from studies using differential staining methods, sperm karyotyping, and in situ hybridisation. So far each of these techniques has ...

An aliquot of spermatozoa retrieved from the epididymis or the testis was washed three times in phosphate buffered saline (pH 7.2) and centrifuged at 650 g for 10 min. The sediment was then fixed in ...

Sex chromosomes are chromosomes, or packages of DNA, that are found inside the nucleus of all of your cells. There are two different kinds: X and Y, which determine whether you’re biologically male ...

Now that certain human disorders have been linked with chromosome abnormalities, it is desirable to examine large numbers of cells for such abnormalities. A computer regime has been devised for the ...

WALNUT CREEK, CA-- Four years after publicly revealing the official draft human genetic sequence, researchers have reached the halfway point in dotting the i's and crossing the t's of the genetic ...

Karyotype analysis includes complete chromosome analysis of at least twenty metaphases with at least two cut karyotypes. The presence or absence of an acquired clonal chromosomal abnormality may aid ...

Scientists warn that the human Y chromosome has lost most of its genes over millions of years, and new research suggests ...

Computational methods used to fill in missing pixels in low-quality images or video also can help scientists provide missing information for how DNA is organized in the cell, computational biologists ...

Scientists remain divided over whether the human Y chromosome will eventually vanish. But clinicians say the real concern ...
