Meiosis: How do you do question 11?

three pairs of chromosomes that were used in Exercise 3 inside the circle on the Simulate synapsis by bringing the members of homologous pairs together to form bivalents). Exchange segments of two non-sister chromatids of each homologous ow crossing over as bivalemo a the mcphase phae nase I: Separate the members of homologous pairs and move them to opposite poles pphase I and Cytokinesis: Form two haploid cells. rophase II: Choose the chromosomes from one pole to undergo meiosis II Metaphase II: Move the remaining chromosomes to the metaphase plate. Anaphase II: Pull the sister chromatids apart at the centromere. Telophase II: Form the haploid daughter cells. 8. What does the term tetrad mean? (Q8) 9. If tetra- means four and bi. means two how can tetrad and bivalent be synonymous? (Q9) 10. What is the significance of crossing over when it occurs between non-sister chro- matids? Can sister chromatids cross over? If sister chromatids cross over, will there be an exchange of different alleles? (Q10) 11.
