Homeotic genes show that insects and vertebrates are closer relatives than the traditional classification system indicates. Homeotic genes display ancient homologies. Homeotic genes of different animal lineages might be ordered in a similar fashion, yet their sequences are completely different. OThe similarity is a coincidence, not documented in other invertebrates and largely a result of random mutations DOCX chology le Review QUESTION 14 0.11364 points Saved Which of the following statements is true about Hox genes experiments? Homeobox regions of the Hox genes allow one species' transcription factor to function in the other species. When the mouse Hox-2.2 gene is experimentally inserted into the fruit fly genome and expressed in the head of developing fruit flies, adults produce legs in place of antennae. When a Hox gene product from an appropriate chromosomal region in chickens was inserted into a fruit fly embryo, it resulted in normal regulation of the fruit fly development. all of the above Screen Shot 15-0...5.28 PM QUESTION 15 0.11364 points Saved Screen Shot 15-0...5.34 PM 1 Deep homology of homeotic genes is also seen in plants. For example, the MADS-box genes have been used to work out phylogenetic relationships within flowering species of plants. What was also documented in these studies across many plant lineages? werina plant specie 19
