Translocation is the movement or rearrangement of something from one place to another. The specific meaning depends on the field:

• In botany and physiology, translocation refers to the movement of soluble substances (like sugars and nutrients) through a plant’s vascular system (phloem and xylem) from sources to sinks.
• In genetics, chromosomal translocation is a structural change where a segment of one chromosome breaks off and reattaches to a different chromosome, which can occur within the same chromosome or between nonhomologous chromosomes. This can be balanced (no net gain or loss of genetic material) or unbalanced (leading to extra or missing genes) and may contribute to diseases such as certain cancers or developmental disorders.

If you’d like, I can tailor these definitions to a specific context (biology class, medical genetics, or plant biology) and include simple examples.
