👉 In biology, homogamy refers to a type of sexual reproduction in which both parents contribute equally to an offspring. This means that both parents are responsible for producing identical copies of their own genes, and the resulting individual is therefore genetically identical to its parents. Homogamy is often used as a metaphor or analogy to describe the concept of natural selection, where individuals with advantageous traits (such as larger size or more complex structures) have a higher chance of survival and reproduction.
