Finer-resolution comparisons are possible by direct DNA sequence comparisons between species. Figure 1 depicts ... Regions of high DNA sequence similarity with human across a 12-kilobase region ...

and similarities in DNA. Students use both morphology and analysis of DNA sequences to identify relationships between species and to organize species and traits into phylogenetic trees.

All genomic DNA samples were treated with RNase A ... of 400 as described previously (Rademaker et al., 2000). The similarity between pairs of combined fingerprints was calculated, and cluster ...
