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

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
Sincerely,
Try the links in the MadSci Library for more information on Genetics.
