Among the six species, the Y chromosome exhibited much more variability than the X chromosome. For example, the X chromosomes of humans and chimpanzees are about 98 percent identical in makeup.

Males tend to only have one copy of the Y chromosome, so it does not have the opportunity to go through genetic recombination, or the "shuffling of genes that occurs in each generation which helps ...

While all human chromosomes contain repeats, more than 30 million letters of the Y chromosome — out of 62.5 million — are repetitive sequences, sometimes called satellite DNA or junk DNA.

The Y chromosome can disappear over time in human males, which may introduce a number of health problems. While the exact trigger for such degeneration is unknown, environmental factors can play a ...

Researchers fully sequence the Y chromosome for the first time Date: August 23, 2023 Source: National Institute of Standards and Technology (NIST) Summary: What was once the final frontier of the ...

Scientists have fully sequenced the Y chromosome for the first time, uncovering information that could have implications for the study of male infertility and other health problems. The first ...

The researchers also observed that this interaction between chromosome background and hormones affected cells’ responses to other stimuli, like an inflammatory stimulus.

In many organisms, X and Y chromosomes can jettison extra material during DNA-swapping sessions with each other. But the campion lost much of its ability to tidy up large parts of its sex ...
