Detailed explanation-1: -Skin problems. Immune system disease. Blood disorders. Neurological, behavioral, and sensory. Hearing and vision. Heart disease. Other organs and systems. Cancer. More items •16-Sept-2010

Detailed explanation-2: -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.

Detailed explanation-3: -But selective breeding, when taken to the extreme, can lead to the development of genetic disorders. And indeed, numerous dog breeds today suffer from severe health issues caused by extreme physical features. Genetic disorders are health problems caused by ‘flaws’ in an individual’s genome.

Detailed explanation-4: -Selective breeding can lead to inbreeding. This is where animals have been mated with close relatives. This results in little variation in a population. As a result, the animals are more likely to have health problems caused by their genes or be more susceptible to certain diseases.

Detailed explanation-5: -Artificial selection/selective breeding has resulted in an increase in the efficiency of the animals and plants we breed, such as increasing milk yield from cows by continuously breeding selected cows with one another to produce a hybrid.
