The Amur tiger genome was predicted to contain 20,226 protein-coding genes and 2,935 non-coding RNAs, and was enriched in olfactory receptor sensitivity, amino-acid transport, and metabolic-related genes, among others. Additionally, researchers found that the Amur tiger genome showed more than 95 percent similarity to the genome of domestic cat.
What is the Amur tiger genome?
The Amur tiger genome is the first reference genome sequenced from the Panthera lineage and the second from the Felidae species. The data from tigers, lions and snow leopards provides a rich and diverse genome resource that could be used in future studies of conservation and population genomics. Genetics underpins the local adaptation and potential inbreeding and/or outbreeding in wild and captive populations can be illuminated and thereby help ensure the future survival of these majestic species.
Why are tigers endangered?
Despite big cats' reputation for ferocity, these majestic species face more danger than they pose: All are endangered, mainly due to habitat loss, poaching, and dwindling food supplies. As the largest felid species on earth, tiger has become one of the world's most endangered species. Understanding of tiger's genetic diversity and demography has been very limited without the whole-genome sequence of tiger, or any of the Panthera species.

How to find karyotype?
This number, along with the visual appearance of the chromosome, is known as the karyotype, and can be found by looking at the chromosomes through a microscope. Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics.

"The tiger trout (Salmo trutta X Salvelinus fontinalis) is a sterile, intergeneric hybrid of the brown trout (Salmo trutta) and the brook trout (Salvelinus fontinalis). The name derives from the pronounced vermiculations, evoking the stripes of a tiger.
