Panicked father

After the baby was born, the panicked Japanese father went to see the obstetrician.

"Doctor," he said, "I don't mind telling you, but I'm a little upset because my daughter has red hair. She can't possibly be mine."

"Nonsense," the doctor said. "Even though you and your wife both have black hair, one of your ancestors may have contributed red hair to the gene pool."

"It isn't possible," the man insisted. "We're pure Asian."

"Well," said the doctor, "let me ask you this. How often do you have sex?"

The man seemed ashamed. "I've been working very hard for the past year. We only made love once or twice a month."

"There you have it!" the doctor said confidently. "It's just rust."

Genetic blueprint

In 1998, scientists announced in the Dec 11 issue of the journal Science that they have deciphered the entire genetic blueprint of an animal - the tiny nematode worm, Caenorhabditis elegans. This is the first time genetic instructions have been spelt out for an animal that, like humans, has a nervous system, digests food, and has sex. The worm's genetic code is spelt out by 97 million genetic letters corresponding to 20,000 genes. This work is a milestone in global efforts to unravel the entire human genetic code - or genome - which is expected to be completed in 2003. The research grew into a collaboration between 1,500 scientists in 250 laboratories worldwide. The efforts were led by John Sulston, in England and Dr Bob Waterston in the U.S.
