heteroploidy

Thân thiện

A scientist examines a cell's chromosomes under a microscope to study heteroploidy.

Definition

1. Noun:
   • The condition of being heteroploid: A state in which an organism or cell has a chromosome number that is not an exact multiple of the haploid number for that species. It refers to an abnormal chromosome complement.

Usage

• The term "heteroploidy" is used in genetics, cytogenetics, and cell biology to describe a chromosomal anomaly. It is a technical, scientific term.
• It is typically used as a subject or object in a sentence when discussing genetic conditions, the results of experiments, or pathological states in cells.

Examples

• Noun:
  • The researchers observed heteroploidy in the cultured cell line, indicating genomic instability.
  • Aneuploidy is a specific and common form of heteroploidy.
  • The condition of heteroploidy can arise from errors during cell division.

Advanced Usage

• "Induction of heteroploidy": A phrase used in experimental biology to describe causing this condition, often through chemical or physical agents.
  • The study focused on the induction of heteroploidy by the toxic compound.

Variants and Related Words

• Heteroploid (adj/noun): Describing or referring to a cell or organism with a heteroploid chromosome number.
  • The heteroploid cells continued to proliferate.
• Aneuploidy (noun): A major subtype of heteroploidy where the chromosome number is not an exact multiple of the haploid set due to missing or extra individual chromosomes.
• Euploidy (noun): The contrasting condition of having chromosome numbers that are exact multiples of the haploid number.

Synonyms

• Chromosomal aberration: A broader term for any deviation from the normal chromosome structure or number.
• Chromosomal numerical abnormality: A more descriptive synonym focusing on the number of chromosomes.

Antonyms

• Euploidy: The state of having a chromosome number that is an exact multiple of the haploid number (e.g., diploid, triploid).
• Diploidy: The specific condition of having two complete sets of chromosomes, the normal state for most somatic cells in animals.
