Chromosomes

This morning, Prof. Alexey Savov, the head of the National Genetic Laboratory SBALAG "Maichin Dom" in Bulgaria, discussed the possibility of individuals with XY chromosomes developing as women. Speaking on Nova TV, he addressed the topic in the context of female boxers competing in the Olympics in Paris this year.

British geneticists have estimated that after a few million years Y chromosome will disappear and male sex with it, writes Science Syndicate.

The male chromosome contains genes that do not seem necessary for life. In particular, the SRY gene, defining the development of the male organism.

Having sex at least once a week slows aging in women – even if they do not enjoy being intimate, new research reveals.
Being active between the sheets increases the length of women’s telomeres, a study found.
These ‘cap’ the end of DNA strands, with longer lengths being associated with slower aging, longer lifespans and improved overall health.

Women who lead a sedentary lifestyle have faster-ageing cells than those who exercise every day, research suggests.
Research on 1,500 women aged 64 to 95 found those who spent many hours sitting and exercised for less than 40 minutes a day had cells that were biologically eight years older.
As people age, their cells age, causing DNA protectors to shorten and fray.
