Scientists have finally decoded mysteries of the Y chromosome. Here’s why it matters

'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 attempt to determine the building blocks of our genetic code took place 20 years ago, but there were still significant gaps left in the sequences of all 23 pairs of human chromosomes. Those blanks were largely filled in last year by an international group of 100 scientists called the Telomere-to-Telomere (T2T) Consortium.

However, over half of the sequences within the Y chromosome, the smallest and most complicated of the 46 human chromosomes, remained unknown. Now, the same group of researchers has filled in the missing information, publishing a complete Y chromosome sequence Wednesday in the journal Nature.'
