Question
The image presents a graph that illustrates the relative fitness of different flower colors under two conditions, potentially representing sympatry and allopatry. The x-axis is labeled "Flower color" with categories: Light blue, Dark blue, Light red, and Dark red. The y-axis is labeled "Relative fitness," with values ranging from 0.0 to 1.0. Key observations: - The left section of the graph (before the dashed vertical line) shows data points for Light blue, Dark blue, Light red, and Dark red flowers. - The right section of the graph (after the dashed vertical line) also shows data points for the same flower colors. Data points and Error Bars: - Light blue flower: Higher relative fitness is shown on the left compared to the right. Error bars indicate variability in both datasets. - Dark blue flower: Moderate fitness on the left with a wider error bar, compared to slightly higher fitness on the right with a narrower error bar. - Light red flower: Higher fitness on both sides, with minimal error. - Dark red flower: Data points are at the higher end of fitness, with little to no error. The Answer Bank indicates terms "sympatry" and "allopatry" which could be used to label the datasets, potentially differentiating the conditions experienced by the flowers. Note: Sympatry refers to populations or species that occur in the same geographic area, while allopatry refers to populations or species that are geographically isolated from each other.

**Flower Color Variation in Phlox drummondii** Flower color variation in *Phlox drummondii* living either in sympatry or allopatry with *Phlox cuspidata* has previously been studied. *Phlox drummondii* exist in four colors: light blue, dark blue, light red, and dark red. Each flower color is controlled by a specific combination of alleles. In allopatry, butterflies randomly pollinate *Phlox drummondii* flowers of all color types. In contrast, non-random pollination occurs between differently colored flowers when both *Phlox* species are living in sympatry. The graph depicts the relative fitness of the alleles that drive flower color in *Phlox drummondii* under conditions of sympatry or allopatry with *Phlox cuspidata*. Label each half of the graph with the term sympatry or allopatry based on the observed trend in the relative fitness of the alleles that control all four flower colors in *Phlox drummondii*.
