Selective breeding has taking place in humans alot throughout history. Depending on the culture of the people and /or during times of slavery. The problem with that ofcourse is that it limits the genetic pool. You don't want that I mean look at West Virginia

Back to fish, for a school project I suggest using hardy live bearers with clearly defined traits such as swordtails, sailfin mollies, lyretail mollies, or guppies.
Then decide what trait you wish to discourage/encourage and how many groups you will use (you will need at least three tanks). You can give the culls away to students or feed them to something.
One way tto do a project like this is to pick a group of fancy guppies that show both 1/2 black and delta tail tendencies. As they breed seperate out 4 groups, the ones that look like the parents, the ones that emphasize the delta tail, the one that strongly show as 1/2 blacks, and the plainer ones. Repeat through several generations, discarding cripples. Keep track of population growth and cull #s. You should end up with a large population of plains (showing little color and smallish tails), a medium population that look like the original population, and 2 lesser groups (one of delta tails and one of 1/2 blacks).
You can get your students to do Mendel charts and also show that the highest ratio of culls and lowest fecundity will occur in the more specialized groups. In junior high I had a nice group of eyespot penpoint guppies that came out of a project like this.

Thanks a lot
Well, I have handed it in.
It wasn't a hands on lab project though, although I'll talk to the teacher about it, maybe, well anything to be able to take some fish to school. I was going to keep a crawdad in my locker but decided against it. So currently i keep a rotting squash.
Anywho, all I had to do was make a poster with lots of information and visuals, aswell has a summary of all the important points and a small report on the main facts.
I used a few of the replies to this thread as examples, credited the owners and cited MFK, maybe if its displayed we'll get a few hits, not likely anyone will take much interest to a biology poster though.
Thanks again for all of the help.
We are going to be doing a culminating task that will probably involve genetics so I'll probably choose selective breeding again and go with Guppy's suggestion, definetly sounds cool. I already have a few mollies and swords i could potentially use,
Unless of course my scarlet kribensis breed
thanks again to everyone.
(I also drew a few suggestive pics on the poster, it is breeding afterall
)
