A population of wildflowers contains 51%51\%51% red-flowered plants. The allele for red flowers (R\text{R}R) is dominant over the allele for white flowers (r\text{r}r).
Use the Hardy–Weinberg equation to calculate the percentage of plants in this population that are heterozygous (Rr\text{Rr}Rr) for flower color.
