State the stage of meiosis of a cell if it contains pairs of chromosomes as shown in the diagram. [1 mark] At the end of meiosis, each of the chromatids shown in the diagram will be in a different haploid cell. The diagrams below represent the chromatids inside the haploid cells. Dete...
Meiosis is a core event of sexual reproduction. The premeiotic DNA replication followed by meiosis prophase I (MPI) are the first critical stages of the meiotic process. During these stages, the meiotic programme diverges from the mitotic programme, and multiple meiosis-specific features are coordin...

Meiosis has the same four steps as mitosis (prophase, metaphase, anaphaseandtelophase) but includes two successive divisions that result in four daughter cells instead of two, each with 23 chromosomes instead of 46. This is enabled by the markedly different mechanics ofmeiosis 1andmeiosis 2. The...

B Schematic representation of chromosome pairing and MSCI dynamics during prophase I progression. Description of general patterns is based on evidence in mouse meiosis (adapted from Waters and Ruiz-Herrera 2020). C The formation and repair of DSBs occurs in the context of the SC (Adapted from ...
Prophase I Metaphase I Anaphase I Telophase I Meiosis Meiosis is the process where 4 genetically unique haploid daughter cells are produced. These are produced in the sexual organs, creating sperm in men and oocytes in females. During meiosis I, h...
(SC) mediates the pairing of homologous chromosomes during the early stages of meiotic prophase I and cohesin proteins play a role in sister chromatid cohesion. However, the absence of the SC and reduction of cohesin complex genes does not preclude meiotic capability in Symbiodiniaceae; similar ...
Meiosis in higher vertebrates shows a dramatic sexual dimorphism: germ cells enter meiosis and arrest at prophase I during embryogenesis in females, whereas in males they enter mitotic arrest during embryogenesis and enter meiosis only after birth. Here we report the molecular analysis of meiosis onse...
