Latest Meiosis Stories
In textbooks, the grand-finale of cell division is the tug-of-war fought inside dividing cells as duplicated pairs of chromosomes get dragged in opposite directions into daughter cells.
First win for Singapore in annual GE Healthcare Life Sciences cell imaging competition
Mating and meiosis – the specialized cell division that reduces the number of chromosomes in a cell – are related, but in most yeasts they are regulated separately.
The Y chromosome is a symbol of maleness, present only in males and encoding genes important for male reproduction. But live mouse offspring can be generated with assisted reproduction using germ cells from males with the Y chromosome contribution limited to only two genes: the testis determinant factor Sry and the spermatogonial proliferation factor Eif2s3y.
Is your biological clock about to run out? While women have always thought they are born with all of the eggs they need, new research says, that’s not true!
A compelling new genetic study tracing the origins of immature egg cells, or 'oocytes', from the embryonic period throughout adulthood adds new information to a growing controversy.
Scientists of KIT and the University of Birmingham have identified relevant new functions of a gene that plays a crucial role in Fanconi anemia, a life-threatening disease.
Researchers at the University of California, Davis have discovered a key tool that helps sperm and eggs develop exactly 23 chromosomes each.
After more than a century of study, mysteries still remain about the process of meiosis—a special type of cell division that helps insure genetic diversity in sexually-reproducing organisms.
In children with genomic disorders, often a gamete – egg or sperm – has gone disastrously awry with either a duplication or deletion of genetic material that results in physical and neurological problems for the subsequent child.
