- The distinctions between the COVID-19 case profiles from China and North America may be due to regional variations in host, environmental, and healthcare-related factors.

Answer: Selective breeding
Explanation:
Selective breeding or artificial breeding is a process that allows humans to select parents in plants and animals that have desirable traits. Such parents are bred to produce offspring that have desirable traits from both parents. Humans have bred many species of plants and animals to improve the quality of plant and animal yields in terms of crops, milk, meat, eggs, and other derivatives.
