The horse genome was first sequenced in 2006. The Horse Genome Project mapped 2.7 billion DNA base pairs, [1] and released the full map in 2009. [2] The horse genome is larger than the dog genome, but smaller than the human genome or the bovine genome. [2] It encompasses 31 pairs of autosomes and one sex chromosome pair. [3]
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.
Living equids show wide variation in the number of chromosomes, ranging from a diploid number of 32 chromosomes in the mountain zebra to 66 in Przewalski's horse. This is due to several chromosomal fusion and fission events during the evolution of equids. [10] The zebra has between 32 and 46 chromosomes depending on the species.
The mule is a domestic equine hybrid between a donkey and a horse.It is the offspring of a male donkey (a jack) and a female horse (a mare). [1] [2] The horse and the donkey are different species, with different numbers of chromosomes; of the two possible first-generation hybrids between them, the mule is easier to obtain and more common than the hinny, which is the offspring of a male horse ...
Equine coat color genetics determine a horse's coat color. Many colors are possible, but all variations are produced by changes in only a few genes . Bay is the most common color of horse, [ 2 ] followed by black and chestnut.

Equus (/ ˈ ɛ k w ə s, ˈ iː k w ə s /) [3] is a genus of mammals in the family Equidae, which includes horses, asses, and zebras.Within the Equidae, Equus is the only recognized extant genus, comprising seven living species.
Champagne is a dominant trait, based on a mutation in the SLC36A1 gene. [1] A horse with either one or two champagne genes will show the effects of the gene equally. However, if a horse is homozygous for a dominant gene, it will always pass the gene on to all of its offspring, while if the horse is heterozygous for the gene, the offspring will not always inherit the color.
