Nothing makes you feel older than finding out everyting you were taught
isn't true anymore.

Well it's simple Kathy, I was kicked out of science class for turning on
the Bunson Burners ( in a 3rd world class in Africa)

Anyway it's all in the genes. If you don't gnome the mutant then leave it
to the odor receptors!

HaH!

Scientists sequenced the genome of the honeybee.

In this article the reporter writes "Among the novelties of the
honeybee,
Apis mellifera, are its 170 genes for odor receptors."

(snip)

But if this is the first time a species' genome has been looked at
and if
there are only 5 other insects that have had their genome cracked,
much less
studied, then 'How do they know?"

By comparison with known odor receptor genes in fruit flies,
Drosophila melanogaster. It doesn't actually matter how many
insects have had their genomes sequenced. What matters is that
fruitflies have been sequenced, AND their genes have been mutated
to see what they do.

Yep. We bioinformatics geeks do this all the time. It doesn't much
matter that we haven't figured out all the honeybee genes, it does
matter that we know a lot about related genes in other organisms.

The 170 genes were probably mostly predicted computationally. We
know what coding DNA looks like from experience with other
organisms. We assume that it is similar in 'unknown' organisms. It
is a computational model (probably several different ones) that of
course isn't perfect. Perhaps some of those 170 genes aren't real,
or slightly mis-predicted. But we might have missed a few, too.

1) There is always room for one more orchid
2) There is always room for two more orchids
2a) See rule 1
3) When one has insufficient credit to obtain more
orchids, obtain more credit
