A horticulturalist wants to produce geraniums with specific characteristics. She knows that the trait of red flowers is governed by the allele R (RR and Rr) and the trait of white flowers is governed by the allele r (rr).

What do the letters in each box of a Punnett square tell you?

The letters in a Punnett square indicate the potential genotypes of offspring from the parental alleles. The square facilitates predictions of phenotypic ratios for traits showing incomplete dominance, like the geranium example where the heterozygote has pink flowers.

Explanation:

The letters in each box of a Punnett square represent the possible genotypes of offspring resulting from a cross between two parents. These letters are the alleles they receive from their parents. For example, in a monohybrid cross involving flower color, if we have one parent with the genotype RR (red flowers) and another with the genotype rr (white flowers), the possible genotypes of their offspring would be represented in the Punnett square.

When determining the outcome of a genetic cross, the Punnett square allows us to visualize all possible combinations of alleles from each parent. If the trait in question exhibits incomplete dominance, such as in the geranium example provided where the R allele for red and the r allele for white blend to produce pink flowers in the heterozygote Rr, the Punnett square is especially useful. It helps predict the phenotypic ratios of the offspring by showing which genotypic combinations will result in which phenotype.
