It turns out that there is an organism that has matching mistakes in its beta-globin pseudogene.

后来发现有一具有与人类相匹配的“β球蛋白假基因遗错误”。

But if the gene copy contains disabling typos or is missing pieces of the original, such as the promoter, it will become a pseudogene.

但如果基因出现短缺（像是缺失启）序列发错误使基因损坏，它们就成了伪基因。
