When people think of DNA, they usually think of genes, the parts that code for proteins and drive inherited traits. But there ...

Binary polymorphisms associated with the non-recombining region of the human Y chromosome (NRY) preserve the paternal genetic legacy of our species that has persisted to the present, permitting ...

Using GENEHUNTER, a maximal multipoint lod score (HLOD) of 4.4 was obtained on chromosome 19q13.3-qter at α (proportion of linked families) = 0.7. A 15 cM critical region is defined by recombinations ...

The Vanishing Y Chromosome: Unraveling Its Impact on Men’s Health and Aging New Delhi, June 21 : For decades, the Y chromosome has been understood as the crucial genetic determinant of male ...

Scientists are expressing concerns about male reproductive health due to the Y chromosome's genetic material loss, potentially disappearing in 11 million years. A study revealed a sharp decline in ...

Flip open a high-school biology textbook, and the rule seems tidy: two X chromosomes mean girl, and an X paired with a Y means boy. That much smaller Y chromosome carries the SRY gene, which is the ...

Men inherit their Y chromosome much the way families pass down a favorite pocketknife – practically unchanged from father to son. For decades, biologists treated this tiny stretch of DNA as little ...
