“Now that we have this 100 percent complete sequence of the Y chromosome, we can identify and explore numerous genetic variations that could be impacting human traits and disease in a way that ...

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 work reveals a complete catalog of the genes in the male sex chromosome — the last human chromosome to be fully sequenced — and how they're organized.. The findings, published Wednesday ...

The Y chromosome, along with the X chromosome, is often discussed for its role in sexual development. While these chromosomes play a central role, the factors involved in human sexual development are ...

The Y chromosome, which determines the sex of human and other mammal babies, is slowly degenerating and may disappear within a few million years, raising fears of extinction. However, a 2022 study ...

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 first human genome was completed in April 2003, but it left behind some unknown gaps, including swathes of the Y chromosome. The chromosome’s repetition made it a challenge to reconstruct.

Miga and Adam Phillippy, the co-leader of T2T and a senior author on the Y chromosome study, initially came together to launch the consortium after working together in 2018, using ultralong reads to ...

The human Y did once contain as many genes as the X chromosome, but has lost them in the past 166 million years. As a result, most of the Y today is made up of repetitive "junk DNA ." ...

For many years, the human Y chromosome was terra incognita. Scientists completed the genetic sequences of other chromosomes, the threadlike structures that hold an organism’s DNA. But more than ...

The human Y chromosome, responsible for determining male sex, finally has gotten an end-to-end examination. The Y chromosome is the smallest of the human chromosomes. “In the old time, people ...

This complete Y chromosome has 106 protein-coding genes, which is 41 more than in the reference genome. But almost all these extra genes are just copies of one gene called TSPY.. At the same time ...
