mixoploid — noun

1.nounC2
Definition

a living thing whose body contains cells with two or more different counts of chromosome sets, so its tissues are genetically mixed rather than uniform.

Example

Zola, a geneticist in Lagos, showed that the patient was a mixoploid carrying both normal and triploid cells.

is a mixoploid + carrying [cell-type] cells

Some plants grown from rescued seeds turn out to be mixoploids in the lab.

plural use: turn out to be mixoploids

Common collocations
  • diagnosed as a mixoploid
  • true mixoploid
  • mixoploid plant
  • mixoploid embryo
Synonyms
  • chimera

    broader; covers any organism with two genetically distinct cell lines, including from fused embryos

  • mosaic

    closely related; usually implies the difference arose after fertilisation in one organism

Antonyms
  • euploid

    an organism whose cells all carry the standard chromosome count

Grammar Patterns

a mixoploid + with/of + cell description

Usage Note

Specialist term used in genetics and clinical cytology. The subject is always a whole organism (person, animal, plant), not a single cell — describe the cells inside the organism, not the organism's parts as mixoploid.

Common Mistakes

Her left arm is a mixoploid.
She is a mixoploid because her left arm has cells with different chromosome counts.
the term labels the whole organism, not one body part.
The blood sample was a mixoploid.
The blood sample came from a mixoploid.
a sample is not itself a mixoploid; the organism it came from is.

Synonym discussion

Sense: noun/1

These four terms describe how an organism's cells compare in chromosome count. A mixoploid is the narrowest label: it specifically means cells with two or more different ploidy levels (for example, diploid plus triploid) coexisting in one body. A chimera is broader and older, covering any single organism built from genetically distinct cell lines, often after two embryos merged. A mosaic usually means the difference arose by mutation after fertilisation, within one body; geneticists often treat mixoploid as one kind of chromosomal mosaic. Euploid is the opposite category, used when every cell carries the species' normal chromosome set. In practice, doctors say 'the patient is a mosaic' in casual notes, but 'mixoploid' on a formal cytogenetic report when ploidy counts vary between cells.

Etymology

GreekModern Latin (scientific coinage)English

Built in the early 20th century from Greek 'mixis' (mixing) plus 'ploid' (the suffix from 'haploid' / 'diploid' meaning 'fold' or 'set of chromosomes'). The word follows the same naming pattern as 'polyploid' and 'aneuploid', signalling a mixed set of chromosome counts inside one organism.
