Học thuậtThân thiện
Definition
- Noun:
- The condition of being diploid: The state in which a cell or organism possesses two complete sets of chromosomes, one from each parent. This is the typical chromosomal condition for the somatic (body) cells of most animals and many plants.
Usage
- General Use: The term is used in biology and genetics to describe the chromosomal constitution of a cell or organism.
- Context: It is typically used in scientific, academic, or educational contexts when discussing cell biology, reproduction, or genetics.
Examples
- Noun:
- Diploidy is the normal state for human somatic cells, which contain 46 chromosomes.
- The fusion of gametes restores diploidy in the zygote.
- Some plants can exhibit both haploidy and diploidy at different stages of their life cycle.
Advanced Usage
- "Maintain diploidy": Refers to the cellular processes that preserve the double chromosome set.
- Mitosis is the cell division process that maintains diploidy in daughter cells.
- "Restore diploidy": Describes the event, typically fertilization, that re-establishes the diploid chromosome number.
- Fertilization restores diploidy by combining haploid gametes.
Variants and Related Words
- Diploid (adj): Having two complete sets of chromosomes.
- A diploid cell contains paired chromosomes.
- Haploidy (n): The condition of having a single set of chromosomes.
- Gametes, like sperm and egg cells, are in a state of haploidy.
Synonyms
- Double chromosome set: A descriptive phrase for the condition.
- 2n condition: A symbolic notation used in genetics, where 'n' represents one set of chromosomes and '2n' signifies the diploid state.
Antonyms
- Haploidy: The condition of having a single set of chromosomes.
- Polyploidy: The condition of having more than two complete sets of chromosomes (e.g., triploidy, tetraploidy).
