During which sub-stage of Prophase I do chromosomes start pairing together through a process called synapsis?
Show answer and explanation
Correct answer: Zygotene
In the zygotene stage, homologous chromosomes begin to pair up side-by-side. This association is accompanied by the formation of a complex structure called the synaptonemal complex.
