What is Selective exclusion?

Selective exclusion is a concept in various fields, including Biology and sociology, referring to the practice of intentionally excluding certain individuals or groups based on specific criteria. In biology, it can describe how certain organisms or cells selectively allow or block the entry of substances, such as nutrients or toxins. In a social context, it may involve the exclusion of individuals from certain opportunities or resources based on characteristics like race, gender, or socioeconomic status. This practice raises ethical concerns regarding fairness and equality.
