Reduction Selective

Reduction selective (also called maturation division selective) is the process by which homologous chromosomes are separated unevenly during meiotic cell division. As a result, one of the daughter cells receives more of one of the pair of chromosomes, while the other receives more of the second chromosome of this pair.

Thus, during selective reduction, the regular distribution of chromosomes between daughter cells is disrupted, which leads to different genetic information in these cells. This process plays an important role in ensuring the genetic diversity of germ cells and subsequently offspring.

Selective reduction is often observed in plants, fungi and some invertebrates. This process does not occur in mammals and birds.
