This document discusses Gregor Mendel's experiments with hybridization using pea plants. It provides background on Mendel and why he chose to use pea plants for his experiments. Pea plants were ideal because they are easy to selectively cross-pollinate. The document outlines the steps Mendel took to perform hybridization, including selecting parent plants with different traits, removing stamen from female flowers, collecting pollen from male flowers, pollinating female flowers, and growing the offspring seeds.
