The Influence Of Genetic Traits In A Dog

When dog owners identify an interesting trait in a dog, Some owners would breed that in hope that the trait would be passed on. After many times of this situation happening, (especially where two dogs with the same trait are bred with each other) traits become fixed. If you can understand the genetics, you can start to predict on what you will see in a crossbreed.
As of now there are over four hundred breeds of dogs and all are maintained as pure-bred stocks through selective breeding, which aims to maintain a closed genetic lineage. Most of the dog traits follow simple genetic rules. Traits from dogs are often referred to as being dominant or recessive. Just like humans, dogs have two copies of one gene (one which came from the mother …show more content…
In combination, the effect when all three are found together is a coat like a poodle. In many cases, the effects of differences in other genes can influence each other. For example, many variants of dog coat colors and patterning behave like this, so predicting the exact colors of offspring can be hard as there are many combinations possible. Breed standards are often used to define a breed and are used to maintain a particular combination of gene versions and combinations. Other traits get carried along with the blocks of genetic material of chromosome housing a gene for a particular trait. Many of which are not wanted or even desirable. Hence many dogs also develop unusual diseases (many of which look very similar to human diseases). Many develop disease including heart disease, cataracts, cancers, deafness and hip dysplasia. This is because genetic mutations that cause these have also been carried along or fixed into these breeds through continual selective
