The haploid genome is about three billion base pairs long (3,000 Mb distributed over 19 autosomal chromosomes plus 1 respectively 2 sex chromosomes), therefore equal to the size of the human genome. [ citation needed ] Estimating the number of genes contained in the mouse genome is difficult, in part because the definition of a gene is still ...
The house mouse is best identified by the sharp notch in its upper front teeth. Skull of Mus musculus - MHNT. House mice have an adult body length (nose to base of tail) of 7.5–10 centimetres (3–4 in) and a tail length of 5–10 cm (2–4 in).
The Japanese house mouse or Japanese wild mouse (Mus musculus molossinus) is a type of house mouse that originated in Japan. Genetically, it is a hybrid between the southeastern Asian house mouse (M. m. castaneus) and the eastern European house mouse (M. m. musculus).
GenomeInfo for short, this template produces a table describing the information about the genome of a given organism. Template parameters [Edit template data] This template prefers block formatting of parameters. Parameter Description Type Status image image Karyotype, for instance Example File:Example.png Unknown optional image_size image_size no description Unknown optional caption caption ...
The red viscacha rat (Tympanoctomys barrerae) has a record C-value among mammals—9.2 pg. [18] Although tetrapoidy was first proposed to be a reason for its high genome size and diploid chromosome number, Svartman et al. [19] showed that the high genome size was due to the enormous amplification of heterochromatin.
The best known mouse species is the common house mouse (Mus musculus). Mice are also popular as pets. In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter. Mice are typically distinguished from rats by their size.
Comparative genomics starts with basic comparisons of genome size and gene density. For instance, genome size is important for coding capacity and possibly for regulatory reasons. High gene density facilitates genome annotation, analysis of environmental selection. By contrast, low gene density hampers the mapping of genetic disease as in the ...
Other popular model organism databases include Mouse Genome Informatics for the laboratory mouse, Mus musculus, the Rat Genome Database for Rattus, ZFIN for Danio Rerio (zebrafish), PomBase [4] for the fission yeast Schizosaccharomyces pombe, FlyBase for Drosophila, WormBase for the nematodes Caenorhabditis elegans and Caenorhabditis briggsae ...
