Question 4 The sequenced genomes of many vertebrates have multiple Hox gene clusters. Why might these have been selectively advantageous in the evolution of vertebrates? A In case of a Hox mutation, an embryo more likely to be able to develop normally. B Having multiple Hox clusters ensures proper mouth-first gastrulation of the zygote. C Having multiple Hox clusters allows vertebrates to evolve faster. Lambryo will be able to evolve new traits.
