PATHOLOGY

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: -The problem with selective breeding is a lack of variation. Selective breeding reduces the number of alleles (genetic differences) in a population. This leaves a population vulnerable to sudden changes in the environment and disease.

Detailed explanation-5: -It leads to loss of variety. It risks creating new diseases. It has no control over genetic mutations. It causes original plant traits to be lost. It causes discomfort to animals. It could create a genetic depression. 09-Sept-2015
