The figure illustrаtes the phylоgeny оf the number оf Hox gene clusters in vаrious аnimal groups. In the phylogeny, the groups [BLANK-1] and tetrapods show gene duplication events. Deletion of hox genes can be best seen in [BLANK-2]. The three possible fates of the genes from these duplication events are [BLANK-3], [BLANK-4], and [BLANK-5]. Based on this phylogeny, the presence of hox genes is a [BLANK-6] trait. * Please note that I need to review your answers, as some of them can be reordered and still remain correct.
