Two purebred lines of plants are crossed together, and the F1 is self-crossed to produce the F2. The graphs below depict four possible distributions of seed weight in the F2. Each graph represents what the seed weight distribution would look like with different numbers of genes controlling it and different amounts of environmental influence. Is this statement correct? True/False: Assume all four populations (each represented by one graph) experience the same natural selection for heavier seeds. When comparing the different F2 distributions, an allele that increased seed weight would be under the weakest selective pressure in the scenario depicted by Graph 4. Graph 4 1 L 10 15 20 25 30 35 Weight (mg) (Each bell curve is a different genotype)
