Freaky factoid: The suppressed genes "are closely related to Hox genes, which play a similar role in humans."

辣妈factoid：抑制基因与同源盒基因相似，它在人类中发挥类似的作用在。

Shrunken limbs and missing digits are likely due to changes in the Hox genes, which determine the development of lower body segments.

缩小的肢体和消失的趾头很可能是由于基因的变化而造成的，这决定了下肢的演化过程。

Homeobox genes (Hox genes) are some highly conserved DNA sequences on the chromosomes. The protein products of Hox genes, as transcription factors, are also highly conserved.

基因是存在于染色体上的一段高度保守序列，其蛋白产物作为转录因子也是高度保守的。
