A hybrid zone comprising staggered chromosomal clines in the house mouse (Mus musculus domesticus).
In the vicinity of John o'Groats (Caithness, Scotland) there is a small karyotypic race of the house mouse (Mus musculus domesticus) characterized by a diploid number of 32 chromosomes, including the metacentrics 4.10, 9.12, 6.13 and 11.14. This race forms a hybrid zone with the standard British race (fully acrocentric chromosomes, 2n = 40). Although hybrid zones normally consist of several (or...
متن کاملMitochondrial DNA variation and the evolution of Robertsonian chromosomal races of house mice, Mus domesticus.
The house mouse, Mus domesticus, includes many distinct Robertsonian (Rb) chromosomal races with diploid numbers from 2n = 22 to 2n = 38. Although these races are highly differentiated karyotypically, they are otherwise indistinguishable from standard karyotype (i.e., 2n = 40) mice, and consequently their evolutionary histories are not well understood. We have examined mitochondrial DNA (mtDNA)...
متن کاملChromosomal heterozygosity and fertility in house mice (Mus musculus domesticus) from Northern Italy.
Following the discovery of over 40 Robertsonian (Rb) races of Mus musculus domesticus in Europe and North Africa, the house mouse has been studied extensively as an ideal model to determine the chromosomal changes that may cause or accompany speciation. Current models of chromosomal speciation are based on the assumption that heterozygous individuals have a particularly low fertility, although ...
متن کاملGastrulation in Mus musculus (common house mouse)
As mice embryos develop, they undergo a stage of development called gastrulation [7]. The hallmark of vertebrate gastrulation [7] is the reorganization of the inner cell mass [8] (ICM) into the three germ layers [9]: ectoderm [10], mesoderm [11], and endoderm [12]. Mammalian embryogenesis [13] occurs within organisms; therefore, gastrulation [7] was originally described in species with easily o...
