I have a lab where I grew several seeds in Petri Dishes in order to study the inheritance of phenotypes. I need to make Punnets squares with the data I gathered and fill in the chart below. I understand the general idea of the Punnets square but am lost with creating it. I also am not too certain how to do the F2 generation prediction and F2 percentage prediction in the second chart. I am certain I can do the P1 generation %, F1 Generation%, and F2 Generation percentage actual. Not sure if it matters but I started with 10 – P1 seeds but only 9 sprouted, and 40- F2 generation seeds but only 37 sprouted.
