14. 10 When does crossing over occur and why? Meiosis

15. *Prophase 1 when homologous chromosomes undergo synapsis and form a tetrad *for genetic diversity in gametes 10 Meiosis

16. 20 What are the products of meiosis? Meiosis

17. *4 genetically different haploid cells *Sperm/egg cells (gametes) 20 Meiosis

18. 30 Why do homologous chromosomes pair up during prophase 1 of meiosis but never in mitosis? Meiosis

19. *To reduce the number of chromosomes (stays the same in mitosis) *to enable crossing over to occur (stays the same in mitosis) 30 Meiosis

20. 40 What is the law of segregation? Meiosis

21. *separation of chromosomes during anaphase 1 of meiosis. *ensures gametes only have one copy of each allele 40 Meiosis

22. 50 What is the law of independent assortment? Meiosis

23. 50 Chromosomes with different alleles sort independently along the metaphase plate of meiosis 1. Meiosis

24. 10 Meiosis What term is used to describe chromosomes that carry the same genes, just different versions of those genes?

25. Homologous Chromosomes 10 Meiosis

26. 20 When do homologous chromosomes pair up? What happens as a results? Meiosis Meiosis

27. Prophase 1- synapsis occurs, a tetrad forms, enabling crossing over. 20 Meiosis Meiosis

28. 30 What is required before meiosis can occur? Meiosis Meiosis

29. 30 *DNA replication in a diploid cell.

30. 40 Identify the phase of meiosis and explain. Meiosis Meiosis

31. 40 Anaphase 1; *homologous chromosomes separate into individual chromosomes (sister chromatids) *cell is now haploid
