Endogamy, exogamy, and hypergamy are all terms related to marriage
Endogamy: The practice of marrying within a social group, such as a caste, ethnicity, or religion. The word comes from the Greek words endo, meaning “within”, and gamy, meaning “marriage”. It can help preserve cultural practices and kinship ties, but it can also limit genetic diversity and perpetuate social inequalities.
Exogamy: The practice of marrying outside of a social group. Exogamy is the opposite of endogamy.
Hypergamy: The practice of marrying someone of a higher social status or sexual capital than oneself. It’s also known as “dating up” or “marrying up”. In Hindu customs, a bride’s family may assess the groom’s educational level, financial ability, and social status before approving the marriage.

In the egg or pupal stage, development stops completely. In the adult stage, activities such as feeding or reproduction are either completely stopped or significantly reduced.
