(Genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants)
Initial stimulation of these receptors leads to symptoms such as tachycardia, miosis, and tremors.
2
The shrinking of the pupil (miosis) caused by this drug limits your ability to adapt to darkness.
3
As measured by infra-red video pupillography, complete miosis occurred within 3.5 to 4.0 min after the application of DFP.
4
We report the case of a 42-year-old male patient who presented with ipsilateral ptosis and miosis and was subsequently diagnosed with internal carotid artery dissection.
5
In beagles PGF2 alpha-IE induced a strong miosis lasting more than 6 hours; Iloprost-PE had no effect on pupil size.
1
The first stage in the division of the nucleus in the gonotokonts has therefore been termed the reductiondivision.
2
This, however, appeared later as a product of the further evolution of the zygote, and the reductiondivision was correspondingly postponed.
3
Reductiondivision and homotypic nuclear division are included together under the term allotypic nuclear division and are distinguished from the ordinary or typical nuclear division.

1
Recombination is the exchange of information between two homologous chromosomes during meiosis.
2
The key step for faithful chromosome segregation during meiosis is kinetochore assembly.
3
Would she have been willing to risk the random roll of meiosis?
4
In meiosis, recombinant frequencies were reduced by a factor of approximately 10.
5
These findings confirm errors in meiosis as the origin of struma ovarii.
6
An account of meiosis can be found in any basic genetics textbook.
7
The effect of purine on the meiosis of mouse oocytes was studied.
8
Consequently, most Lsd1-null oocytes fail to complete meiosis I and undergo apoptosis.
9
The meiotic error in the mother most probably occurred in meiosis II.
10
In each case the aberration was consistent with a maternal meiosis I error.
11
Pollen grains are the haploid products of meiosis required in fertilization.
12
However, the roles of kinetochores in homologous chromosome segregation during meiosis are ill-defined.
13
Accurate segregation of chromosomes during meiosis requires physical links between homologs.
14
How the selective release of chromosome cohesion is regulated during meiosis remains unclear.
15
Following completion of meiosis, DNA replication must be repressed until fertilization.
16
Here we found that Zwint-1 is required for homologous chromosome segregation during meiosis.
