synapsis
Meiotic chromosome alignment
Synapsis is the pairing of homologous chromosomes during cell division, specifically in meiosis.
The chromosomes align side by side, allowing genetic material to be exchanged between them.
This process is essential for sexual reproduction and genetic diversity: During synapsis, crossing over can shuffle genes between maternal and paternal chromosomes.
