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 ...
A recent study using 89 whole-genome sequences revealed that the modern day Mus musculus castaneus emerged from an ancestral Mus musculus population in Indian subcontinent some time around 700 kya. From there, this ancestral population migrated to Iran around 360 kya to form Mus musculus domesticus and then to Afghanistan around 260 kya to form ...
The genetically modified mouse in which a gene affecting hair growth has been knocked out (left) shown next to a normal lab mouse. 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.
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.

The C57BL/6 mouse was the second-ever mammalian species to have its entire genome published. [ 1 ] The dark coat makes the mouse strain convenient for creating transgenic mice: it is crossed with a light-furred 129 mouse, and the desirable crosses can be easily identified by their mixed coat colors.
The genus Mus or typical mice refers to a specific genus of muroid rodents, all typically called mice (the adjective "muroid" comes from the word "Muroidea", which is a large superfamily of rodents, including mice, rats, voles, hamsters, gerbils, and many other relatives), though the term can be used for other rodents.
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.
