The Punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. The Punnett square below examines the chance of offspring having freckles, which is a dominant trait. A Punnett square is shown. The columns are labeled Upper F and f. The rows are labeled Upper F and f. Clockwise from upper left the boxes contain: Upper F Upper F, Upper F f, Upper F f, f f.

Based on the Punnett square, what is the probability that the offspring will have freckles?
