Fruit Flies

Post by prmccar » Fri Nov 27, 2009 4:30 pm

Does anybody know why fruit flies are the best thing to test genetics on?

lifespan of the fruit fly is relatively short and makes observing many generations of a trait easier. Also, specific traits such as eye color and body color/shape are easily observed and quiet easy trace through generations.

Thanks,

That was the information that I was looking for.

Also, they are pretty small (like Arabidopsis), so you can have thousands of them in small volume. Also their chromosomes are big to watch under microscope

Cis or trans? That's what matters.

they do need to be cared as much as others like peas and others

if you want to make a cross between 2 then its easier cause they are small.
and unlike peas you do not need to carefully cover the stigmas and transfer pollens and so on.
it isn't what you do that matters but it is how you do it

Have you ever worked with something so small? It's definitively not easier! Just try to seed Arabidopsis, that really sucks :twisted: But with fruit flies it's easier, that they do the work by themselves ;)
And the reason, why to choose FF instead of peas for example has to do, in accordance to my opinion, with that they are animals, as we are...

Also, I read once that they have a genome similar to that of humans and other animals?

They don't take a long time to produce offspring, their genomes can be manipulated easily, they have four relatively large pairs of chromosomes. You can tell the difference between males and females pretty easily. They're cheap to feed and take care of.
