– Study from the University of Kent reveals Y chromosome is dwindling, raising concerns about potential extinction of males in the future
– Y chromosome is responsible for male sex determination and carries the SRY gene
– Y chromosome has limited gene repertoire, compared to X chromosome
– Y chromosome lacks genetic recombination, leading to degeneration over time
– Y chromosome shows adaptability with palindromes to repair damaged genes
– Concern for human reproduction as Y chromosome essential for sperm production
– Possibility of genetic engineering for assisted reproduction in the future
– Y chromosome disappearance predicted to happen 4.6 million years into the future, leading to new system of sex determination or reproduction.
