0 the type of cell division that happens as part of reproduction (= the process of producing young animals or plants), in which one cell divides into four gametes (= reproductive cells), each with a different mixture of chromosomes and half the number contained in the original cell
1 the type of cell division in which one cell divides into four gametes (= male or female cells that join to form an organism), each with a different mixture of chromosomes (= cell structures) and half the number as were in the original cell
Meiosis in protists : recent advances and persisting problems.
The rest of the mutations were clearly generated during meiosis and occurred in tetrads with any progenitor alleles.
We wanted to find out whether such treatment affects the ability of the egg to complete the meiosis and to transform nuclei of spermatozoa.
Immature oocytes contained intact germinal vesicles; mature oocytes resumed meiosis and had undergone germinal vesicle breakdown.
We conclude that this mechanism has probably already developed by the time the germ cells have become committed to meiosis.
Our results here indicate that this factor or factors may have developed by the time the germ cells have become committed to meiosis.
As growth is completed, transcription becomes silent, and sufficient molecules are stored in the oocytes for meiosis and full developmental competence.
Effect of prematuration, meiosis activating sterol and enriched maturation medium on the nuclear maturation and competence to development of calf oocytes.
