A study conducted by a research team at the Crick Institute identified important genes on the Y chromosome that regulate ...

Chromosome abnormality is the condition in a cell or organism where the number of chromosomes or the structure of any chromosome differs from the normal karyotype. When the variant genotype is not ...

People with shorter telomeres, the protective caps at the end of chromosomes, inside their white blood cells may be more likely to have strokes or develop dementia and late-life depression, ...

The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the biological sex, reproductive organs, and sexual characteristics that develop in a person.

Meiosis II resembles a mitotic division, except that the chromosome number has been reduced by half. Thus, the products of meiosis II are four haploid cells that contain a single copy of each ...

In particular, balanced translocations and inversions can neither be identified by microarrays since they do not alter chromosome copy numbers, nor by short-read sequencing because of the ...
