Professor of Human Genetics, Bryan Sykes (oxfordancestors(1)),
discussed his alarming forecast that male extinction is
inevitable, due to thethe rapidly decaying â€œYâ€ chromosome. He
estimated that this would occur within 5,000 generations or
125,000 to 150,000 years from now, and that male infertility
(currently at around 7%) will continue to rise over time. The
problem, he explained, stems from the fact that the Y chromosome
doesn't exchange DNA like other chromosomes and is thus prone to
higher level of mutations. Additionally, Sykes posited a virtual
battle of the sexes in which men's Y chromosomes are locked in a
"deeply imbedded war" with the mitochondrial DNA of females,
each seeking to exclusively reproduce themselves at the expense
of the other.He hypothesized that male homosexuality could be a
kind of "genetic altruism," that furthers the agenda of the
mitochondrial DNA. The Y chromosome's weakening might be
arrested by using genetic manipulation to remove certain genes,
suggested Sykes. Cloning ho
