There are excellent references on the Web re: Punnett Squares, including:

The MIT Biology Hypertextbook

The Biology Project at Arizona

If you still have questions after looking at these references, please let me know!

BTW, traits are dominant if you see their phenotype in the heterozygote. For example:

If I cross a pure breeding green pea with a pure breeding yellow pea and all of the offspring are green, then green is dominant and yellow is recessive.

Please feel free to e-mail me if you have any other questions, or if these on-line resources don't give you the information you need
