The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the gray wolf.Also called the domestic dog, it was selectively bred from an extinct population of wolves during the Late Pleistocene by hunter-gatherers.
A pedigree chart is a diagram that shows the occurrence of certain traits through different generations of a family, [1] [2] most commonly for humans, show dogs, and race horses. [ citation needed ] Definition
A Czechoslovakian Wolfdog. The domestic dog (Canis familiaris) is a domesticated species of the gray wolf (Canis lupus), along with the dingo (Canis lupus dingo).Therefore, crosses between these species are biologically unremarkable and not a hybridization in the same sense as an interbreeding between different species of Canidae.
In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his Systema Naturae the binomial nomenclature – or the two-word naming – of species. Canis is the Latin word meaning "dog", [3] and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals.
A genome sequence is the complete list of the nucleotides (A, C, G, and T for DNA genomes) that make up all the chromosomes of an individual or a species. Within a ...
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.
A study of dog remains indicates that these were selectively bred to be either as sled dogs or as hunting dogs, which implies that a sled dog standard and a hunting dog standard existed at that time. The optimal maximum size for a sled dog is 20–25 kg based on thermo-regulation, and the ancient sled dogs were between 16 and 25 kg.
The Himalayan wolf (Canis lupus chanco) is a canine of debated taxonomy. [3] It is distinguished by its genetic markers, with mitochondrial DNA indicating that it is genetically basal to the Holarctic grey wolf, genetically the same wolf as the Tibetan and Mongolian wolf, [4] [5] [3] and has an association with the African wolf (Canis lupaster).
