Definition
- Noun:
- (Biology/Genetics): A zygote is the initial cell formed when two gamete cells (a sperm cell and an egg cell) fuse during fertilization. It contains a complete set of chromosomes, one from each parent, and is the earliest stage of development for a new organism.
Usage Examples
- Noun:
- The zygote begins to divide rapidly after fertilization.
- In humans, the zygote travels down the fallopian tube toward the uterus.
- The study focused on the genetic material within the single-celled zygote.
Advanced Usage
- "Zygote formation": The process of fertilization leading to the creation of a zygote.
- Zygote formation marks the beginning of embryonic development.
- "Zygote intrafallopian transfer (ZIFT)": A type of assisted reproductive technology.
- ZIFT involves placing a zygote directly into a fallopian tube.
Variants and Related Words
- Zygotic (adj): Pertaining to or of the nature of a zygote.
- The zygotic stage is crucial for genetic determination.
- Zygotene (n): A stage in meiosis, the process that creates gametes. While related to reproduction, it is a distinct biological term.
- Blastocyst (n): A later stage of embryonic development that follows the zygote stage.
Synonyms
- Fertilized egg: A common, less technical term for a zygote.
- Oosphere (in botany): Specifically in plants, the female gamete which, after fertilization, becomes the oospore (analogous to a zygote).
Related Phrases
