Table 1: Comparative genome sizes of humans and other model organisms [2] Organism Estimated size (base pairs) Chromosome number Estimated gene number Human (Homo sapiens) 3.1 billion: 46: 25,000 Mouse (Mus musculus) 2.9 billion: 40: 25,000 Bovine : 2.86 billion [6] 60 [7] 22,000 [8] Fruit fly (Drosophila melanogater) 165 million: 8: 13,000
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 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.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
Mus musculus [1] [2] Linnaeus, 1758. Mus is a subgenus of the rodent genus Mus. Species. Little Indian field mouse, Mus booduga (Pakistan, India, Sri Lanka ...
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).
A genetically modified mouse, genetically engineered mouse model (GEMM) [1] or transgenic mouse is a mouse (Mus musculus) that has had its genome altered through the use of genetic engineering techniques. Genetically modified mice are commonly used for research or as animal models of human diseases and are also used for research on genes.
