Answer:
Hox genes are space-temporally expressed and thus play a major role in determining body organization during embryo development of animals
Explanation:
The Hox genes are evolutionarily conserved genes that encode major transcription factors during animal development, which are involved in the expression of target genes that regulate the formation of different parts of the body along the anteroposterior body axis. These genes contain an evolutionarily conserved DNA sequence called the homeobox. Hox genes are often organized in clusters that are space-temporally (sequentially) expressed during animal development, thereby inducing the formation of specific structures in the correct places of the body. The co-linear expression pattern of these clusters functions to ensure a normal developmental fate along the anteroposterior axis.
