Monoploidia is a specialized term used almost exclusively in scientific and academic contexts, particularly in genetics, plant biology, and agricultural research. It is not commonly used in casual conversation in either Brazil or Portugal, remaining confined to university curricula, research publications, and specialized biological discussions. The term reflects the international nature of scientific vocabulary, with minimal regional variation.
