Answer:
C. Possible outcome of a cross
Step-by-step explanation:
A Punnett square is a tool used in genetics to predict the probable outcomes of a cross between two organisms. It is a visual representation of the possible combinations of alleles from each parent that could be passed on to their offspring. The Punnett square is used to calculate the probability of each genotype and phenotype in the offspring, based on the alleles of the parents. It does not determine the actual outcome of a cross, but rather predicts the probabilities of different outcomes.
