Final answer:
A punnett square is a four-square box used to do genetic problems by predicting the possible combinations of genes in offspring.
Step-by-step explanation:
The four-square box that is used to do genetic problems is called a punnett square. It is a tool used by biologists to predict the possible combinations of genes that can be present in the offspring of a mating pair. The punnett square is divided into four boxes, with each box representing a possible combination of genes from the parents.
