WebCorrect option is C) The meiosis occurs in two stages meiosis I and meiosis II. Meiosis I is characterised by the pairing of homologous chromosomes, crossing over between homologous chromosomes and separation of homologous chromosomes, so that each daughter cell produced after meiosis I have one-half the chromosome number as … The tetrad is the four spores produced after meiosis of a yeast or other Ascomycota, Chlamydomonas or other alga, or a plant. After parent haploids mate, they produce diploids. Under appropriate environmental conditions, diploids sporulate and undergo meiosis. The meiotic products, spores, remain packaged in the parental cell body to produce the tetrad.
