The evolution of gene families is a fundamental aspect of understanding biological diversity and the mechanisms that drive evolutionary change. Gene families arise when genes undergo duplication events, producing multiple copies of a gene within a genome. These duplications provide raw material for evolution, allowing one copy to maintain the original function while others accumulate mutations that can lead to novel functions or regulatory patterns. This process contributes significantly to the adaptability and complexity of organisms. Gene duplication can occur through various mechanisms, including unequal crossing over during meiosis, retrotransposition, or whole-genome duplication. Once duplication has occurred, the
