Final answer:
As world travel becomes easier and human populations intermix, the reduction in genetic and cultural diversity is likely. This leads to less genetic diseases common in isolated populations and fosters the creation of a more homogeneous global culture and increased international cooperation on health issues.
Step-by-step explanation:
As world travel becomes easier and human populations intermix, the occurrence of homogenization of genetic and cultural diversity will probably decrease. This phenomenon refers to the reduction in genetic variation and cultural distinctiveness that occurs when populations from different regions interbreed and intermix their cultural practices. While this can lead to a more unified global community, it can also result in a loss of traditional cultures and unique genetic traits. However, such increased connectivity can also foster international cooperation in addressing global health issues, including pandemics, through the sharing of medical data and resources to contain the spread of diseases.
The occurrence of genetic diseases specific to certain populations may also decrease, as genes are more widely dispersed and the genetic pool becomes more diverse. This can potentially decrease the frequency of certain hereditary diseases that are more common in isolated populations. Additionally, with increased globalization, there's a possibility of creating a more homogeneous global culture as different languages and customs blend together.
