we turn back to linkage mapping in model organisms. The important thing to realize about linkage is that it helps researchers identify the locations on chromosomes at which specific genes exist.

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 ...

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.

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 ...

Researchers at Kyushu University have revealed how spatial distance between specific regions of DNA is linked to bursts of ...

A recent study characterizes the ZW sex chromosomes in Amborella trichopoda, revealing insights into sex determination and ...

"The Y chromosome has many sections that repeat, and even some that are palindromes -- the same forwards and backwards. It makes it challenging to understand which genes are encoded there ...

Drive mechanisms in B chromosome systems have been studied in many species and contexts using various technologies, from classical genetics to cytogenetics. But despite being an ideal test case to ...
