Homeotic genes contain a homeobox sequence that is highly conserved among very diverse species. The homeobox is the code for that domain of a protein that binds to DNA in a regulatory developmental process. Therefore, you would expect that _____. - ️️homeotic genes are selectively expressed as an organism develops A current view of how the human and chimpanzee can share most of their nucleotide sequence yet exhibit significant phenotypic differences is that many of the most important sequen...
