Sex determination at birth is decided on the chromosomes the baby has. A female has two X chromosomes, whereas a male has one X and one Y chromosome. According to Medline Plus, in every cell, humans ...

Human biological sex is determined by the sex chromosomes X and Y. In most cases, females possess two X chromosomes, while males have one X and one Y. However, there is some evidence that the Y ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

Chromosomes are blocks of DNA (deoxyribonucleic acid). They contain very detailed and specific instructions that determine: How the cells in a baby's body develop. What features the baby will have, ...

The chromosome associated with male development, which is the last mysterious piece of the human genome, has been fully sequenced by a team of more than 100 researchers around the world, including ...

A look at the brains of an endangered spiny rat off the coast of Japan by University of Missouri (MU) Bond Life Sciences Center scientist Cheryl Rosenfeld could illuminate the subtle genetic ...

In what might be a surprise for some, the male sex chromosome is far more complex than its female counterpart. This is why it’s taken scientists so long to work out exactly what makes a male a male.

Researchers from Skoltech, the University of Potsdam, and the Massachusetts Institute of Technology have discovered a ...

The Y chromosome may be a symbol of masculinity, but it is becoming increasingly clear that it is anything but strong and enduring. Although it carries the “master switch” gene, SRY, that determines ...

Spatial interactions between RNA, architectural factors and chromatin have essential roles during X-chromosome inactivation. CTCF is a versatile factor that regulates chromosome counting, allelic ...

Abnormalities in the structure of chromosomes within someone’s genetic makeup are called structural chromosomal abnormalities. Robertsonian translocations are very rare structural chromosomal ...
