Prospects for Comparative Genome Analyses Among Mammals
The discovery of hypervariable microsatellite markers and the technical advances of marker typing has facilitated efforts towards the construction of genetic linkage maps in several diverse vertebrate species. These mapping projects have advanced the exploration of each organism’s genome and its biology. But less effort has been focused on the mapping of coding genes, genetic markers which allow comparisons of genome organization across species. The establishment of universal Type I (coding gene) genetic markers, which can be mapped in all species, will allow true comparisons of genome organization across species and will provide the framework for comparative genetic research (O’Brien, 1991). Comparative genetics allows the gene poor species to consider the information of gene rich species, exponentially increasing the perspective available for disease and genetic trait analyses. In developing the genetic map of the cat (O’Brien and Nash; Nash and O’Brien; Gilbert et al., 1988; O’Brien et al., 1988), we have focused on the mapping of Type I markers in order to capture the information locked in the genome of other species and to assist the use of the feline genome in evolutionary and inherited disease research (O’Brien et al., 1993).
