5. the pairing up of homologous chromosomes during prophase i is called s______
6. when synapsis happens, the group of 4 chromatid arms is called a t______
7. during oogenesis, one egg cell and three p____ b____ are produced.
8. the production of mature sperm cells is called s______
9. independent assortment happens during a______ of meiosis.
10. organisms used m______ for growth, repairing injuries, and replacing worn out cells.
11. type of cell division in which genetic recombination occurs = m______
12. interphase ii is different than interphase of mitosis because the cell skips s phase and does not copy its d____ in meiosis.
13. the production of mature eggs is called o______
14. synapsis and crossing over occur during p______ of meiosis.
15. a h______ cell has only one copy of each chromosome,

meiosis starts with? kelly riedell/brookings biology

Explanation:

1. Independent assortment describes maternal/paternal chromosome mixing in Anaphase I.
2. Meiosis converts diploid (2n) cells to 4 haploid cells.
3. Crossing over is DNA exchange between homologs in Prophase I.
4. Gametes are reproductive cells (sperm/eggs).
5. Synapsis is pairing of homologous chromosomes in Prophase I.
6. A tetrad is 4 chromatids from synapsed homologs.
7. Oogenesis produces 1 egg and 3 polar bodies.
8. Spermatogenesis makes mature sperm.
9. Independent assortment occurs in Anaphase I.
10. Mitosis functions in growth/repair.
11. Meiosis involves genetic recombination.
12. Interphase II skips DNA replication (S phase).
13. Oogenesis produces mature eggs.
14. Synapsis/crossing over happen in Prophase I.
15. Haploid cells have one chromosome copy.
