step for a successful meiosis. The processes of DNA repair and chiasma formation that take place following synapsis have consequences at many levels, from cellular survival through to impacts upon evolution itself.

Mechanisms of homologous chromosome cohesion

Homologous chromosomes are held together by several mechanisms during meiosis, ensuring their proper pairing, alignment, and recombination. These mechanisms include:

# The synaptonemal complex (SC) is a key protein structure that physically holds homologous
