A recent study revealed the shrinkage of Y chromosomes, raising the concern of the offspring of males. Swipe to Know what Y chromosomes are and how their shrinkage affects human health and genetic inheritance.
CHROMOSOMES
Humans contain 46 chromosomes (23 pairs), out of which the last 23rd pair of chromosomes is known as the sex chromosome. Females have only XX chromosomes, while males have a combination of XY chromosomes.
SEX DETERMINATION
As females have only X chromosomes, the development of the foetus's sex depends on the father. The combination of the mother's X and father's Y chromosomes (XY) indicates the growth of a male child.
Y CHROMOSOME
Yes, chromosome Y is responsible for the development of the male gene, and it transfers the genetics of the father to his son.
SHRINKAGE OF Y CHROMOSOMES
The study published by Proceedings of the National Academy of Sciences decodes that the 'Y chromosome' is shrinking and will disappear in approximately 11 million years.
ARE MEN FUTURE IS IN DANGER?
The study suggests that humans will also develop a new sex-determine gene like the Spiny Rat (Rodent Species, Japan) who developed a new sex-determine gene.
