Hi Crystal!
Punnett squares are very useful once you figure out how to
use them. Here is a useful site I found on using Punnett squares:
http://www.borg.com/~lubehawk/psquare.htm
It talks a bit about dominant, recessive and hybrid traits.
Also, if you have more specific questions, I would be happy
to answer them.

Hi Crystal, here is a fun website that looked helpful
http://www.borg.com/~lubehawk/psquare.htm
And here is one that is interactive and gives lots of possible
types of
crosses http://www.athro.com/evo/gen/punexam.html
And another http://anthro.palomar.edu/mendel/mendel_2.htm
There are many! Here is a list of dominant and recessive human
traits
although many of these are not single gene traits but are
inherited
polygenically.

There are many other lists in other organisms like fruit flies,
cows,
horses etc. Good luck!

Just put "Punnett Square" into google. Lots of tutorials
come up to explain the process. The very first one on the
list seemed quite good: http://www.borg.com/~lubehawk/psquare.htm
