Wooden tweezers

The wooden tweezers, carved from a single lath of linden wood and smoothed by the oils of my palm, grasp the thin filament of a stamen in the St. Thomas Abbey garden on this sweltering July afternoon in 1858. Each yellow grain of pollen is a discrete unit of potentiality. Transferring these grains to the stigma of a white-flowering Pisum sativum requires a steady hand and a mechanical indifference to the individual plant. The act of counting begins long before the harvest. It begins with the tally of successful crosses. One flower is a singular event. Ten flowers are a morning’s labor. One hundred flowers are the threshold of a population.

The seeds from this cross will be uniform. They will all bear the purple hue of the dominant parent. This uniformity is a mask. To see the true nature of the inheritance, the second generation must be allowed to self-fertilize. The garden beds become a physical ledger. In one plot, the plants are tall; in another, they are dwarf. There are no intermediates. The counting changes the gardener’s perception of the plant from a living creature into a data point. When the seeds are gathered, they are sorted into bowls. The smooth seeds click against the ceramic. The wrinkled seeds are silent.

Five thousand four hundred and seventy-four smooth seeds. One thousand eight hundred and fifty wrinkled seeds. The individual seed is a mystery. The population is a law. The ratio is 2.96 to 1. This is not quite 3 to 1, but the deviation is a function of the sample size. At n=10, the ratio is chaotic and misleading. At n=7000, the noise of the individual case recedes and the mathematical structure of the germ emerges. The wrinkled seed is not lost in the first generation; it is merely latent. It waits for the count to reach a sufficient magnitude to reveal its presence. The truth of the trait is only visible when the individual is sacrificed to the sum. I will record the final tallies in the ledger tonight.
