I know how to make a punit square for genetics, but how would you make a double punit square?????
Thank you!
A AaBbxAaBb cross is shown
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
In short, along the top you have spots for two letters in four places. All the different combinations of the two traits for each allele are put in a different spot on both sides, then you combine them. AB and AB makes AABB. An aB and Ab makes AaBb.
