Each pair consisted of one cross-fertilized plant and one self-fertilized plant which germinated at the same time and grew in the same pot. The plants were measured at a fixed time after planting and the difference in heights between the cross- and self-fertilized plants are recorded in eighths of an inch. </p> <h3>Usage</h3> <pre> darwin </pre> <h3>Format</h3> <p>This data frame contains the following column: </p> <dl> <dt><code>y</code></dt><dd> <p>The difference in heights for the pairs of plants (in units of 0.125 inches). </p> </dd></dl> <h3>Source</h3> <p>The data were obtained from </p> <p>Fisher, R.A.
