Heretogamy is a marriage between two individuals from distinct social and ethnic backgrounds. Homogamy is a type of assortative mating in which the marriage of two individuals is decided by societal factors such as financial status, gender, faith, tribe, language, and color, among others. Homogamy is also known as "breeding within the family." When two people are homogeneous in these characteristics, they are more apt to be compatible than two people from varied cultures.
People all over the world choose their spouses based on certain characteristics that they think will lead to a successful union. These characteristics can include schooling, income, religion, politics, beliefs, hobbies, and so on. The sort of homogamy that exists in a particular culture is knownas structural homogamy. For example, in some societies, males favor women with blond hair and blue eyes, whereas in others, appearance is less important than wealth and prestige. Structural homogamy is merely the propensity of people to choose mates who share comparable characteristics. It can be seen in many real-life marriages where each spouse is drawn to the other's characteristics even if they are unaware of it.
