Risks of selective breeding include:
- reduced genetic variation can lead to attack by specific insects or disease, which could be extremely destructive.
- rare disease genes can be unknowingly selected as part of a positive trait, leading to problems with specific organisms, eg a high percentage of Dalmatian dogs are deaf.

What are pros and cons of selective breeding?
Selective breeding is an extremely efficient way to good genetics in certain crops and livestock. However, if you are concerned about the cons of it, such as a genetic depression or discomfort to animals, the alternatives can be much worse, such as carrying out genetic modification.
How is selective breeding harmful to dogs?
Selective breeding and genetic disorders
This process involves the selection and breeding of animals with desirable characteristics, leading to offspring that inherit the same traits. But selective breeding, when taken to the extreme, can lead to the development of genetic disorders.
What are the risks and ethical concerns surrounding artificial selection?
Artificial selection in animals raised for consumption is unethical and harmful to both the animals being selected as well as the producers who raise them. An unfamiliar environment is needed to domesticate animals to suit human needs, causing both psychological and physical stress.
What is the limitation of selection in relation to breeding?
A selection limit indicates that the population has reached the point where further change is no longer feasible. This can be due to the fact that there is no more genetic variation, but there are other reasons.
What dogs are affected by selective breeding?
English Settlers, Dalmatians, and Australian Cattle Dogs are the main carriers of this genetic defect magnified by selective breeding. Another sense affected by breeding is vision. Siberian Huskies, Samoyeds, and Bichon Frise are dogs that suffer from a hereditary form of cataracts as they get older.
How has selective breeding negatively affected pugs?
The pug was selectively bred to feature an extremely flat face, which contributes to breathing difficulties and eye injuries. Disorders like hip dysplasia, commonly seen in large purebreds, such as German Shepherds have emerged due to the breeder's desire for a sloping back.
How have German Shepherds been negatively affected by selective breeding?
But now, a recent study out the UK shows how German Shepherd dogs also exhibit the health issues that selective breeding can cause. ... Arthritis, hip dysplasia, cancer, degenerative spinal disorders, and osteoarthritis are some of the health issues that German Shepherds and other selectively bred dogs are predisposed to.
What are some advantages and disadvantages to artificial selection?
Able to produce crops with higher yield, shorter harvest time, higher resistance to pest and diseases and better taste in an inefficient yet somewhat natural way. 3. No safety issues such as those brought about by genetic engineering.
How does selective breeding affect natural selection?
New varieties
Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
What are some pros and cons of genetically modified organisms?
The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.
