Scientists have taken an important step forward in understanding the human genome - our genetic blueprint - by fully deciphering the enigmatic Y chromosome present in males, an achievement that could help guide research on infertility in men.
- our genetic blueprint - by fully deciphering the enigmatic Y chromosome present in males, an achievement that could help guide research on infertility in men.
The Y chromosome's genes help govern crucial reproductive functions including sperm production, formally called spermatogenesis, and are even involved in cancer risk and severity. But this chromosome had proven difficult to crack owing to its exceptionally complex structure. "This is especially important because the Y chromosome has been traditionally excluded from many studies of human diseases," UCSC genomicist and study co-author Monika Cechova said.
