Some men spend their lives trying to work it out. Others simply give up.But scientists believe they have finally come up with an explanation about the way a woman's mind works.
That legendary feminine unpredictability has its basis in genetics, a study has found.
Certain genes that influence human personality and behaviour vary more widely in women than in men.
This makes it much harder to work out what any individual woman will be like.
While women have two X chromosomes, scientists have long believed genes are "randomly silenced" on one of these.
This is to avoid so-called "double dosing", having two genes that fulfil the same role.
The latest research, however, shows that 15 per cent of these genes are not actually silenced in women.
A further 10 per cent are active in some but not others.
Scientists say the findings mean women do get "double doses" of some genes after all.
Many are linked to the risk of various diseases but some help determine personality traits.
So if, for example, there was a gene on the X chromosome for happiness, this would mean women vary more greatly in how happy they are likely to be than men.
Whereas men would either have a healthy copy of the gene or not, women have the possibility of two working copies making them more happy.
So in a group of 100 women, there would be far more variation in happiness, moodiness, aggression or any trait affected by genetics than among 100 men.
"This could mean that women are much more variable than men," Professor Robin Lovell-Badge, head of developmental genetics at the National Institute for Medical Research, said.
"They could have greater variations in their susceptibility to disease but also in their behaviour and physical appearance.
"I always thought they were more interesting."
The findings come from a study, published in the journal Nature, in which scientists at the Wellcome Trust Sanger Institute in England genetically sequenced the human X chromosome.
If you could make one wish for yourself, not including anyone else, what would it be?
As for me, it's hard to pin it down to one, as there are so many, but I guess I wish I hadn't gotten married when I did. Reversing the effects is hard when you
As all my Dxpnet friends visit this board I thought I will appeal here. Kindly mention your birth dates in your profiles. This way we can have birthday bashes right here ;)
Just to let all the Duncan gang know that Freebird has asked me to let you know - that no, she hasn't flown away forever!!!....however, she has had massive problems with her computer and just can't log on to the board.
You wouldn't believe how many people have told me this. Is it because they can't cope with knowledge? I have never believed this phrase because everyone is raised with a certain amount of knowledge of something from birth. Every time a bit of knowledge is
I?m bored. Bored with life, bored with society, bored with retarded people, and most of all bored with this planet, it sucks. Don?t think so,? then you haven?t been paying attention.
Having endured the last few years of the Bush reign of Error,
About 2 days ago, a friend of mine who is engaged confided in me that he was getting cold feet. Not because he doesn't love his lady-friend, but more-so, he was wondering why he should get married at all. In his opinion, marriage is entirely about the wo
International Women's Day is the story of ordinary women as makers of history; it is rooted in the centuries-old struggle of women to participate in society on an equal footing w
