Notes on Usage

• Technical Term: "Dị nhiễm" is a highly specialized, technical term used almost exclusively in academic, genetic, and biological contexts. It is not used in everyday conversation.
• Clarity: In most modern Vietnamese scientific texts, the term "nhiễm sắc thể giới tính" (sex chromosome) is preferred for clarity. "Dị nhiễm" may be encountered in older or very specific technical literature.
