Incest.

Inbreeding is the process of mating closely related individuals within a population or a breeding line. It often occurs within animal or plant populations and can lead to a reduction in genetic diversity. The most common example of inbreeding is the mating between siblings, but it can also occur between parents and offspring, or other close relatives.

To get an example of inbreeding, you can explore various sources such as scientific papers, books, or online resources. You can search for specific animal species known for inbreeding, such as some dog breeds, where breeding with close relatives may be practiced to maintain certain desirable traits. Another example would be selective breeding in agriculture, where plants with specific traits are repeatedly bred with each other to create a population with uniform characteristics.

Overall, it's important to note that while some intentional inbreeding occurs in certain contexts for specific purposes, it can have negative consequences on the overall health and genetic diversity of a population.
