Comment	It has been estimated (646) that alpha-Amy-B2 contains three or four genes. The alternative states of Amy 7B2, namely, Amy 7B2 and Amy 7B2^m^ (761), are identical to the variation in band 2 (278). The complete description of the alpha-Amy-B2 variation also includes variation in band 11 (278).
