New Research Finds: Y Chromosome Still Stable - Neon Tommy

NIST

The Y chromosome, which determines whether a mammal will be a male has been found being stable for the past 25 million years, according to a new research published in the journal Nature. 

Compared to the larger X chromosome, the Y pales both in size and the amount of genes it contains.In the last 1950s, many geneticists predicted that the Y chromosome probably would be vanishing in 10 millions years for "very few expressed genes actually resided on the Y." Such an idea led people wonder wether there would be males any more.

David Page, one author of the new paper, and his colleagues questioned the idea and examined the evolutionary history of the Y chromosome.They found that the Y still remains many genes that are indispensable to the survival of human beings.
