Dogs have a wide variety of genes that influence color, character, and behavior. Further, the same genes may give a very different effect on different types and lengths of coats. The following information about genetics in general, new genetic technologies, and how we improve the species with this technology should give you a good idea about why this is so important. .
One of the biggest problems people have with genetics is the assumption that a defined trait - size, ear type, color, yappiness - is due to a single gene. In fact, genes code for two types of things. One, which is relatively well understood, is the structure of a particular protein. The normal equivalent of the albino gene, for instance, codes for tyrosinase, an enzyme which breaks up the amino acid tyrosine as a first step in producing melanin, the major pigment in mammalian skin and hair. In an albino, this enzyme cannot be produced, and as a result melanin cannot be produced. A second type of gene controls when and where other genes are turned on or off. These genes are the subject of vigorous ongoing study, and probably have a major impact on such things on the number of vertebrae in the spine or the age at which growth is complete. Genetic technologies will help increase the information we already know about genetics in canines. .
Knowing a dog's genotype has become more and more imparative for a pet owner to have. In fact, there is actually a company in which u can send information and attain your dog's perment record of their genetic type. This can solve ownership disputes, be used as an ID for your dog, and can be used after the dog is deceased for researching purposes. The price to "DNA type" your dog is about forty dollars. Another genetic technology would be selective cross-breeding. Although humans have cross-bred dogs for centuries now, we have just recently gained a true knowledge for it. By selectively cross-breeding a pet, scientist now know what to expect down to the very hair type and color on its body.
Genetics is a powerful field of science, with many possibilities. ... The actual study of genetics started long ago, with Mendel and his studies. Now scientists know much more of genetics and DNA. ... The Austrian Monk Gregor Mendel discovered the basics of genetics. ... Thus, domesticated animals, such as dogs, differ greatly from their wild brethren, wolves. ...
Some say, as stated in Asimov's New Guide of Science ARTICLE by Isaac Asimov, "There are many kinds of roses, finches, dogs, and horses "but all the roses, finches, dogs, and horses are just that; they never change into daisies, parrots, cats, or cows."" ... According to Mendel's laws of genetics, some offspring was always born with light-colored wings while others had darker wings. ... Because Darwin did not know of modern genetics he thought these birds were all different types and that evolution across types had occurred. ... Scientists acknowledge that all dogs descended f...
Cancer also doesn't most likely hit just boy dogs or girl dogs; it doesn't matter there age either. Although genetics may have a big part in it, the environment around don't help, certain foods researchers say cause cancer. ... Cancer is mostly seen in older dogs on average around the age ten or older. Dogs are seen more often with cancer than cats although. ... Humans and animals have the same rate of receiving cancer, half of dogs over ten are diagnosed with cancer, along with one in four dogs will die from the disease known as cancer. ...
Guide Dogs Images of dogs guiding their masters have been found painted on the ancient Chinese paintings, on the walls of Pompeii, and in Rembrandt etchings from the 17th Century. It was known back then that it was possible to train dogs to guide their blind masters and now schools to train dogs are all over the world. ... Many dogs face a genetic disease called retinal atrophy. ... "The Lab-golden is the result of research by Eldin Leighton, director of canine genetics for Seeing Eye Inc." ... Back 50 years ago, schools for guide dogs were just starting to be founded. ...
The cloning of Dolly was a major achievement in genetics. ... Scientists worked in a number of countries worldwide to clone cows, bulls, horses, pigs, rabbits, mice, rats, cats, dogs, and monkeys (Nardo, 2007). ... Cats and dogs have been cloned to duplicate their deceased pets. ...
Iran Wilmut is a scientist at PPL Therapeutics firm in London. In February of 1997, he was the first scientist in the world to clone an animal. It was a sheep named Dolly. Since then, Wilmut has succeeded in turning a cows" skin cell into a heart cell. "These were the first people to clone an ani...
Physiologists study mammals, mostly mice and rats but also rabbits, cats, dogs, pigs, sheep, goats, monkeys, and chimpanzees" (p. 269). ... Prior to the current revolution in genetics, the only practical method to study the regulation and function of a mammal's genes was to observe diseases and mutations that they developed. ...
Human Genome Project A genome is defined as the complete collection of an organisms genetic material. The human genome is composed of about 50,000 to 100,000 genes located on 23 pairs of chromosomes in a human cell. It is said that a single human chromosome may contain more than 250 million DNA base...
