The name of the sauteur d'Alfort hare comes from the French for "The Jumper of Alfort"
The sauteur d'Alfort, or "Jump of Alfort," is a four-legged creature with a unique running posture. It uses its front legs to lean on the ground while doing acrobatic stances. Then lift the back pair of legs above your head as ทดลองเล่นสล็อต you run forward. Instead of using two hind legs to bounce like a normal rabbit.
Recently, scientists found The disorder is caused by a genetic predisposition. A mutation in some genes makes the spine unable to control movement. or coordinate the movements of the left and right sides of the body accordingly
Dr. Miguel Carneiro from the University of Porto in Portugal. One member of the international research team that studied the subject said: “When it walks slowly, you won't be able to see how it differs from the other rabbits. But when this rabbit tried to speed up It becomes difficult to use two hind legs to jump forward like a normal rabbit. It will flick its hind legs too much and at the wrong time.”
“But these rabbits will learn how to run forward by spilling high. to compensate for the defect of the hind legs Only a few months after being born."
The sauteur d'Alfort rabbit can't use its hind legs to fly up like the typical rabbit in this photo.
The Suter Dalfort is not a species of rabbit. It is an unusual trait that can only be found in some rabbits. by the veterinary school in the city Maisons-Alfort in France as a discoverer and experimented with breeding these six-tall rabbits for a study in 1935.
The research paper, published in the journal PLOS Genetics, said the team had deciphered the entire genetic or genome of the Suter Dalfort rabbit. They were then compared with the genome of a normally running rabbit. This led to a mutation in the RORB gene, which produces nerves in the spine that connect the left side of the body to the right side. And it's a gene that's crucial for controlling limb movement.
The mutated RORB gene has transformed into a recessive gene. This caused these six-tall rabbits to have some nervous system abnormalities since birth. which this inferior trait can be passed on to offspring
The research team also speculates that the RORB gene may be important to the movement of other mammals, including humans. This makes it interesting to continue to study whether an abnormal RORB gene in humans can lead to movement impairment.作者: martina28043 時間: 2021-8-1 16:10
