The fruit is a hairy pod that grows in clusters of three to five, each pod is 3–8 cm (1.2–3.1 in) long and usually contains two to four (rarely more) seeds 5–11 mm in diameter. Soybean seeds come in a wide variety of sizes and hull colors such as black, brown, yellow, and green. Variegated and bicolored seed coats are also common.
In 1997, 81% of all soybeans were of genetically modified stock. This means that genes were changed directly.
In China, going back to the ancient Chou dynasty soy beans were considered to be one of the five sacred foods.
