Genetic screening can curb a lot of genetic defects in a population.
Step-by-step explanation:
A genetic defect in an individual starts from the time the person is in mother’s womb. So, these diseases can be curbed if the person goes through a genetic screening during this time. Any genetic defected womb can be abhorred and thus how we can decrease the number of this disease.
A person with Down’s syndrome doesn’t survive for long, or doesn’t lead a healthy life. So aborting these child isn’t actually bad. Thus we can delete the chances of these babies by means of genetic screening by means of amniocentesis.
