Evaluation of effectiveness of some mitochondrial genes in biosystematics and phylogeographic studies of house mouse (Mus musculus ) subspecies
The identification of the efficiency of some mtDNA genes of Mus musculus species complex (house mouse) for biosystematics research was studied in this approach. Recent studies have made use of different mitochondrial genes including NADH dehydrogenase genes, cytochrome b gene, cytochrome oxidase genes, D-loop region and whole mtDNA genome to study the house mouse species. Usage of each of these...
متن کاملKaryotype of NIH, C57BL/6 and Razi strains of laboratory mice (Mus musculus)
The laboratory mouse is recognized as the pre-eminent model for genetic research. Awareness of chromosomal patterns of experimental animals increases their value for a variety of different fields of study. We aimed to study mitotic chromosome preparations from NIH, C57BL/6 and Razi strains of mice, which are outbred, inbred and partially inbred laboratory mice respectively. Bone marrow cells we...
متن کاملChromosome C-banding in Mus musculus L.1766 Strains Shows a Fixed Position for the Centromere and Variable Amounts in Different Populations
Three subspecies of Mus musculus have been recognized in Iran so far. The house mouse (genus0T 0T2TMus2T, species0T 0T2TMus musculus2T) are recognized for their highly conserved morphology and chromosomal structure, but some chromosomal characters offer accurate taxonomic markers in this species that has been shown any unambiguous diagnostic morphological traits. Among the chromosomal character...
متن کاملAnogenital Distance and Condition as Predictors of Litter Sex Ratio in Two Mouse Species: A Study of the House Mouse (Mus musculus) and Mound-Building Mouse (Mus spicilegus)
The Trivers - Willard hypothesis (1973) suggests that the maternal condition may affect the female's litter size and sex ratio. Since then other factors had been found. Previous findings revealed in the case of some mammalian species, that females with larger anogenital distance have smaller litters, while the sex ratio is male-biased. That has only been demonstrated in laboratory animals, whil...

Mus Musculus was randomly mutagenized using N-ethyl-N-nitrosourea (ENU). Mutations on Chromosome 5 were selected using the Rw inversion, a visibly marked, recessive, lethal inversion that covers almost fifty megabases (Mb). Multiple mutations were isolated from the subsequent three-generation mutagenesis screen, one of which was lethal 6. Using a combination of complementation tests and recombi...
