Get the extra chromosome mug.This is a genetic abnormality that does not have to do with being gay, lesbian, etc. This abnormality is seen when the XY or XX chromosomes have more than the usual X and Ys. This can lead to infertility in males or females and physical traits not normally of that sex. For more information, check the page on biology. about. com about Sex Chromosome Abnormalities.

Get the google chromosome mug.Scientists have discovered that the Y chromosome uses a neat trick to repair its most crucial genes, a strategy that apparently helps keep it from rotting away over evolutionary time.
Instead of doubling up to protect its genetic cargo like other chromosomes, the lone Y safeguards its genes by having sex with itself, an international consortium has found. Proving perhaps that nature has a sense of humor, scientists have discovered that the Y chromosome - the one that makes a man a man - has a remarkable ability to make do-it-yourself repairs.
June 20, 2003 — The human male sex chromosome does have the ability to repair itself and may not be headed for extinction as had previously been thought, according to a surprising new study.
A 40-strong team of researchers led by David Page of the Whitehead Institute at the Massachusetts Institute of Technology, report their findings in this week's issue of the journal Nature.
As well as having a previously unknown and elaborate back-up system for self-repair, the Y chromosome also carries 78 genes.
"The Y chromosome is a hall of mirrors," said Page, whose team has for the first time identified the full genetic sequence of a Y chromosome, from an anonymous donor.
Both the male Y and female X chromosomes are thought to have originally been the same size, but after the Y took on the sex-determining role for maleness it apparently began to lose genes. At this time it also lost the ability to pair up exactly with its partner and to swap faulty genes for good ones, as the other 22 pairs of non-sex chromosomes do.
Earlier studies had suggested that the Y chromosome carried only a few dozen genes, compared with more than 1,000 known on the X chromosome.
A team of Australian researchers led by Jenny Graves, of the Research School of Biological Sciences at the Australian National University in Canberra, previously found that the Y chromosome had been losing five genes per million years. Graves had thus predicted that the chromosome might be heading for extinction within five to 10 million years.
But Page said that the Y's full genome sequence has revealed that scientists generally had underestimated both its number of genes and its powers of self-preservation.
The team believes the Y has developed an apparently unique way of pairing up with itself. They found that many of its 50 million DNA "letters" occur in sequences known as palindromes. Like their grammatical counterparts, these sequences of letters read the same forward as backward but are arranged in opposite directions — like a mirror image — on both strands of the DNA double helix. This means that a back-up copy of each of the genes they contain occurs at each end of the sequence.
When the DNA divides during reproduction, the team believes, it opens an opportunity for genes to be shuffled or swapped and faulty copies to be deleted.

Get the y chromosome mug.Chromosome which is found in both males and females. XY = male. XX = female. Sperm can be either an X or Y chromosome. During fertilization, if the Y chromosome sperm reaches the egg, then the baby is a boy. If the X chromosome sperm reaches the egg, then the baby is a girl.
Think of it as females having two copies of the same CD music album in every cell in their body, while males have one copy of that album in every cell in their body(x chromosome) and an extra single CD (the y chromosome) also in every cell in their body.
Even if the y chromosome was suffering from genetic degredation(which it is not) the effect could easily be reversed by genetic engineering.
