Protein polymorphisms in American deermice (Peromyscus) and genetic linkage homology

摘要: A number of lines evidence developed recently suggest that mammals may share genetic linkage groups in common. This raises the fundamental questions whether there is a basic, underlying "genetic architecture" common to mammals, and this architecture functionally related development. If spatial arrangement loci functional, one would expect chromosomal segments be protected from rearrangements by natural selection, thus evolutionarily conserved. Unfortunately, little information available on detail genome structure mammals. At cytological level, karyotype staining show banding patterns permits identification apparently homologous chromosome arms between certain species. data are for only few laboratory domestic species, man. The mouse, Mus musculus, mammalian species in, which chromosomes have been extensively mapped with markers. [213]
