Answer #1

To study the mutation in highly divergent species insects and mammals , first the highly conserved regions must be studied by alignig them. We already know about the Hox gene or the cdk gene. Such genes must be studied first which are functionally analogous and then the structure can be studied if found t be dissimilar the amino acid sequence is to be studied to under why the variation has occured and what different types of mutations have occurred over time
