hypoploid
Very Low / TechnicalHighly Technical / Scientific
Definition
Meaning
An adjective describing a cell or organism having fewer chromosomes than the typical, characteristic number for its species.
More broadly, it can refer to a state of genomic deficiency or a chromosomal complement that is not an exact multiple of the haploid number, falling below the normal euploid set.
Linguistics
Semantic Notes
Strictly used in genetics, cytogenetics, and related biological sciences. It describes a specific, countable deviation from the norm. It is the opposite of 'hyperploid'.

Examples
By Part of Speech
adjective
British English
- The culture contained a significant proportion of hypoploid cells.
- They identified a hypoploid variant of the wheat strain.
American English
- The tumour biopsy showed a hypoploid chromosome count.
- Researchers are studying the stability of hypoploid genomes.
Examples
By CEFR Level
- Scientists sometimes find hypoploid cells in cancer research.
- A missing chromosome can lead to a hypoploid condition.
- Cytogenetic analysis confirmed the cell line was predominantly hypoploid, with chromosome numbers ranging from 38 to 41.
- The hypoploid state of the embryo likely contributed to its non-viability.
Learning
Memory Aids
Mnemonic
Think: HYPO means 'under' (like hypodermic, goes under the skin). PLOID relates to chromosomes. So, HYPO-PLOID means 'under the normal chromosome count'.
Conceptual Metaphor
A SHORTFALL or DEFICIT in the standard chromosomal blueprint.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'гипоплазия' (hypoplasia - underdevelopment of a tissue).
- The '-ploid' part is directly translatable as '-плоидный', but the term is a direct borrowing: 'гипоплоидный'.
Common Mistakes
- Using it as a noun (e.g., 'a hypoploid') is less common; 'a hypoploid cell' is preferred.
- Confusing it with 'haploid' (having a single set of chromosomes). Haploid is normal for gametes; hypoploid is abnormal for the cell type.

FAQ
Frequently Asked Questions
No, it is a highly specialised term used almost exclusively in genetics and related biological sciences.
'Aneuploid' is the broader umbrella term for any chromosome number that is not an exact multiple of the haploid set. 'Hypoploid' is a specific type of aneuploidy where the number is *below* the normal euploid number.
Yes, though it's more common for cells or cell lines. An organism can be described as hypoploid if a significant proportion of its cells carry the abnormality, or if it arose from a hypoploid zygote, though such organisms are often non-viable.
The direct opposite is 'hyperploid', meaning having more chromosomes than the typical euploid number.
