Definition of germ cell in English: germ cellnoun Biology 1A cell containing half the number of chromosomes of a somatic cell and able to unite with one from the opposite sex to form a new individual; a gamete. Example sentencesExamples - Mutated DNA can only be passed to the next generation if it is present in a germ cell such as spermatozoa and ova, each of which contribute half of the DNA of the new organism.
- Male identity would be a cell-autonomous decision entirely independent of the sexual identity of the soma but dependent upon the number of X chromosomes in the germ cell.
- A mature male or female germ cell usually possessing a haploid chromosome set is capable of initiating formation of a new diploid individual by fusion with a gamete of the opposite sex.
- A majority of the strains examined contained one insertion and the highest number of insertions that occurred in a single germ cell was seven.
- The population has experienced an expansion from a few copies in the single germ cell, and a distribution skewed toward more molecules having several mutations may be expected.
- 1.1 An embryonic cell with the potential of developing into a gamete.
Example sentencesExamples - Of all the stem cells that we use in research, they come from three sources: embryonic stem cells, embryonic germ cells and adult stem cells.
- The follicle is composed of the germ cell, the oocyte, and surrounding follicle cells that originate from the epithelial cells of the germinal epithelium.
- In order to create sperm, the scientists first had to make embryonic germ cells, that in itself a major achievement.
- These types of moles are produced by the development of a germ cell that lacks equal contributions of DNA from both the egg and the sperm.
- Researchers discovered that they could develop primordial germ cells from embryonic stem cells.
