With chromosome maps called idiograms, researchers can pinpoint the locations of genes and locate abnormal gene forms. Aa Aa Aa Most cytogeneticists are skilled at identifying individual ...

But research suggests that the Y chromosome has been rapidly degenerating over the course of our evolution. In fact, the gene may one day disappear altogether. "The early 'proto-Y' chromosome was ...

The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

Females (XX) carry twice as many X-linked genes on their sex chromosomes as males (XY). How do cells control gene expression to manage this potentially lethal dosage problem? A prime example of X ...

The cell's nucleus contains chromosomes. These are long threads of DNA, which are made up of many genes. Humans have around 25,000 genes across their 23 pairs of chromosomes.

Now nonchromosomal genes have been identified by the traditional methods of genetic analysis There has been evidence for many years that hereditary information exists apart from the chromosomal genes.

Some chromosomes, such as B chromosomes, can increase their inheritance rate to their own advantage. These extra chromosomes ...

B chromosomes manipulate cell division for survival, and new research identifies key genes, including DCR28, involved in this ...

Stanford Medicine says that as many as 4 out of 5 people affected with autoimmune diseases are women. Women have two X ...
