Meiosis is the generation of germ cells (eggs and sperm). In meiosis, DNA replication is followed by two division cycles: meiosis I, which segregates homologous chromosomes and meiosis II, which ...

This is an important study examining the role of conserved PCH-2 protein at different stages of C. elegans meiosis. The authors use elegant molecular genetic approaches to provide convincing evidence ...

Such events typically lead to a 3:1 segregation of alleles among the four gametes of a single meiosis. GCs can be associated with COs (CO–GCs) or with NCOs (NCO–GCs) where they can introduce new ...
