Step 1
I'll explain the key events of meiosis I step by step:

Step 2
: Prophase I

- The most complex and important stage of meiosis I - Homologous chromosomes pair up in a process called synapsis - Chromosomes undergo crossing over, where genetic material is exchanged between maternal and paternal chromosomes - This creates genetic variation through recombination - Chromosomes condense and become visible - Nuclear membrane begins to break down

Final Answer

- Two daughter cells are formed - Each cell contains half the original number of chromosomes - Chromosomes are still in their duplicated state - Cell membrane pinches to create two separate cells Final Key Outcome: Two genetically unique haploid daughter cells are produced, each with half the original chromosome number, setting the stage for meiosis II.
