The simple allometry formula y = bxk is often used to describe the relative growth of two parts X and Y of an organism. The allometric constant b can be usefully identified with the relative number of cell division centers (germinal centers) of the two parts, and the allometric constant k can be usefully identified with the relative frequency of cell division of the two parts. This approximation leads to experimentally testable predictions: for example, the developing brains of mammals and birds may have germinal centers not present in the developing brains of fish and reptiles, and the developing brains of humans may differ from the developing brains of monkeys in their rates of cell division.
简单的异速生长公式y = bx^k常被用于描述生物体两个部分X和Y的相对生长。异速生长常数b可以有效地等同于这两个部分细胞分裂中心（生发中心）的相对数量，而异速生长常数k可以有效地等同于这两个部分细胞分裂的相对频率。这种近似得出了可通过实验检验的预测：例如，哺乳动物和鸟类发育中的大脑可能具有鱼类和爬行动物发育中的大脑所没有的生发中心，并且人类发育中的大脑在细胞分裂速率上可能与猴子发育中的大脑有所不同。
