Despite the immense amount of genetic material present in each cell, around 3 billion base pairs in humans, this material ...

There are 23 pairs of chromosomes in the human body. This includes 22 pairs of autosomal or somatic chromosomes that are common to both men and women and one chromosome that differs according to what ...

Basic biology has it that girls are girls because they have two X chromosomes — the things inside cells that carry our genes. Boys are boys because they have one X and one Y. Recently, though, there's ...

The human Y chromosome, the determinant of male sex, has finally been completely sequenced. What it unveils could prove crucial to understanding the Y chromosome’s puzzling origins, and — pertinently ...

Expert says the Y chromosome will disappear in about 125,000 years. LONDON, April 28, 2008— -- Imagine a world without men: Lauren Bacall but no Bogie, Hillary Clinton but no Bill, no Starsky or ...

Sex chromosomes are unusually labile systems, with frequent shifts between male and female heterogamety and with a large variety in the precise number and types of chromosomes. The lability is further ...

A research paper highlights how spiny rats have developed a new male-determining gene. A recent study suggests a surprising future for human reproduction: the Y chromosome, which is crucial for ...

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 ...

Community-developed approach combines multi-contact 3C with HiFi sequencing to deliver haplotype-resolved assemblies from minimal input materialMENLO PARK, Calif., Jan. 08, 2026 (GLOBE NEWSWIRE) -- ...

A study revealed that the Y chromosome, which determines male sex, is degenerating and may vanish in a few million years. Research on Sry-deficient Amami spiny rats, which lost the Y chromosome but ...

The sex we're assigned at birth depends largely on a genetic flip of the coin: X or Y? Two X chromosomes and you (almost always) develop ovaries. An X and a Y chromosome? Testes. These packages of ...
