Meiosis News and Research

RSS

Multicellular eukaryotes and single-celled sex cells reproduce by a process called meiosis. In this process, the number of chromosomes in a mother cell is halved to produce gametes, cells that fuse with other cells. This happens in plants, animals, and fungi. German biologist, Oscar Hertwig first discovered meiosis in sea urchin eggs in 1876.

Experts develop CRISPR-Cas9-mediated inheritance control in male mice

The world’s first CRISPR-Cas9 genetic editing-based strategy to regulate inheritance in mammals was declared nearly three years ago.

Researchers identify a gene in wheat with profound effects on the production of seeds

Scientists from the John Innes Centre have identified a gene that has deep-rooted effects on seed production in wheat.

Three-dimensional organization of genome is extremely dynamic during gamete formation

Inside the nuclei of cells, the genome is tightly organized (packaged). This three-dimensional (3D) genome organization is basic because it controls gene expression.

Research group reveals the essential role of Knl1 gene in plants

Dr. HAN Fangpu's group from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences reports the identification and functional study of the maize Knl1 gene in an article published online in PNAS.

Study uncovers unusual sex chromosomes of Australian iconic animals

The sex chromosomes genetically define the developmental fate of an embryo to become a male or a female individual, and usually, appear as one pair of morphologically different chromosomes between sexes.

Evolutionary biologists discover genomic signatures of recombination in freshwater invertebrates

Skoltech's evolutionary biologists discovered recombination in bdelloid rotifers, microscopic freshwater invertebrates, which have long been regarded as 'an evolutionary scandal' due to their presumed ancient asexuality.

Imperfect egg cells more common than originally thought

AZoLifeSciences speaks to Dr. Terry Hasssold about his latest research into oocytes and how imperfect egg cells are more common than scientists initially thought.

'Survival of the fittest': How meiotic drivers shape the evolution of gamete formation

It can be hard to dispute the common adage 'survival of the fittest'. After all, "most of the genes in the genome are there because they're doing something good," says Sarah Zanders, PhD, assistant investigator at the Stowers Institute for Medical Research
