Dangers of Selective Breeding
Selective breeding can create some problems:

Inbreeding
- Selective breeding can lead to inbreeding. Here, some breeds become particularly susceptible to disease or inherited defects.
- For example, French bulldogs have been selectively bred to have flat faces, but that causes them breathing problems.

Reduced variation
- Selective breeding can reduce variation (differences in characteristics) within a population, making it harder for a species to adapt to environmental change.

French bulldogs have been selectively bred to have flat faces. What problem has this caused as a result of inbreeding?
A breed of dog has been developed by breeding together closely related dogs for many generations. Which problem caused by selective breeding does this describe?
