No, dogs are not genetically modified. Dogs have been selectively bred by humans over thousands of years for specific traits and characteristics.
Throughout history, humans have domesticated and bred dogs for various purposes, such as hunting, herding, and companionship. Selective breeding involves choosing dogs with desired traits, such as appearance, temperament, or ability, and mating them to produce offspring with those same traits.
This process has led to the wide variety of dog breeds that we see today. However, selective breeding is different from genetic modification. Genetic modification involves altering an organism’s DNA in a laboratory to introduce new traits. While genetic modification is common in plants and some animals, it is not typically used in dogs. Instead, dogs have naturally occurring genetic variations within their species, which results in the diversity of breeds that we know and love. These variations are the outcome of natural genetic mutations and the selection of specific traits by humans. Dogs are not genetically modified; they are the product of selective breeding and natural genetic variation.
The Basics Of Canine Genetics
