Answer:Based on the given information and the Punette square, it seems that you are referring to a Punnett square used in genetics to predict the outcome of a cross between two organisms. The Punnett square is a graphical representation that shows all possible combinations of alleles (alternative forms of a gene) for a particular trait.In this case, the Punnett square is incomplete, and the missing information is the pink allele (RW). The pink allele is a combination of the red (R) and white (W) alleles. Therefore, the missing pink allele in the Punnett square is RW.The completed Punnett square would look like this:Pink and pinkRed and pinkWhite and pink
