用法筆記

This sense carries strong negative moral and legal implications. It almost always describes an unjust or discriminatory practice. In historical writing, the passive construction (be segregated by law / by race) is common. Avoid using this sense lightly for non-social types of separation — use 'separate' instead to prevent unintended political overtones.

💡'Segregate' in a non-social context sounds unnecessarily political; use 'separate' for physical arrangements of objects or neutral categories.

Strictly a technical term in genetics and cell biology. The subject is always paired genetic units (alleles, genes, chromosomes), and the process takes place during meiosis. The intransitive use ('alleles segregate') is the standard form; transitive use ('the cell segregates the alleles') is rare and considered less precise.

常見錯誤

💡The genetic sense of 'segregate' only applies to allele/gene separation during meiosis, not to general cell division of bacteria.

💡In genetics textbooks, 'segregation' refers specifically to meiosis, not mitosis.
