Same types of genes: genes with similar sequences. Comparison of staining patterns of chromosomes suggested no conservation didn"t look alike. After both genomes were sequenced, each mouse chromosome could be pieced together from different human chromosomes o. All the different pieces of the genome are there, but the organization of it is different. Unique to animals: no o o o o. Start with 1 genome and all the chromosomes are laid out and pieced together with another organism"s chromosome. These pieces sometimes have to be broken up and the different chromosomes are on different locations. Can break up the chromosomes and put them back together. Collinearity: can pull behind the different information from different genomes from different places. Almost the same with both mouse and human. When comparing both genomes as a whole: o o. Break the mouse genome in 100s of fragments but they can be aligned with the human genome.
