Answer 1

Select:
- Through crossing over
- Through independent assortment

Brief why: Crossing over (prophase I) exchanges alleles between homologous chromosomes; independent assortment (metaphase I) randomly distributes maternal and paternal homologs to gametes. Binary fission and mitosis do not generate the same meiotic shuffling.
