RESUMO
A murine linkage map generated from analyses of 428 meiotic events in an interspecific cross and pulsed field gel electrophoresis allowed examination of the genomic organization of a 6000 kb segment of mouse and human chromosome 1. Analysis of five genes within this syntenic segment of both species revealed striking conservation of gene order, intergenic distance and, to a lesser extent, CpG dinucleotides. In the mouse, meiotic crossover events were not evenly distributed; a hot spot for meiotic recombination was coincident with a CpG-island. These studies provide a practical approach to aid physical mapping of the human genome and a model for determining the molecular principles that govern meiotic recombination. In addition, these findings demonstrate profound conservation of genomic organization over mammalian evolution.
