Thus, human chromosome 7 appears to be composed of sequences that are largely conserved in the mouse genome (Figure 12-26), but the mouse sequences homo-logous to human chromosome 7 are split into 19 blocks located on six different chromosomes. Thus comparative genomics reveals that chromosomal rearrangement, to be fully discussed in Chapter 15, is a key mechanism in chromosomal evolution. The process of evolution can be considered the longest-term genetic experiment that we have available to us. We are just learning to use the power of comparative genomics to help decipher the in-formation encrypted in a genome. The effects of genomics on biological research Even though genomics as a technology and an approach is not even 20 years old, it has already become an aca- demic household word. The analysis of whole genomes
