DNA does not replicate in this stage 3. spores produced by meiosis of plant cells 4. gametogenesis the production of gametes 5. spermatogenesis meiosis in males, production of sperm 6. oogenesis meiosis in females, occurs in ovaries and produces eggs 7. zygote formed when sperm meets egg and fertilization event occurs, result of conception 8. primary oocyte a cell that divides to form the polar body and the secondary oocyte, meiosis 1 occurs to theese cells, when meiosis 1 is compleyed, a polar body is made and shrives to become nonfunctional 9. oogonium cell which undergoes chromosome replication to produce an oocyte, starter non- functional egg cells 10. secondary oocyte begins meiosis 2 but stops at metaphase, looks to meet sperm in fallopian tube, results in another polar body forming if meiosis 2 is completed 11. polar body may either disintegrate or divide again, they are a way to dispose chromosomes while retaining lots of cytoplasm in the egg 12. nondisjunction failure of chromosomes to seperate which results in gain or loss of chromsomes 13. eupliody a correct number of chromsomes in a species 14. aneuploidy a change in the chromosome number from nondisjunction 1/2  ap bio meiosis part 2 Study online at https://quizlet.com/_gjzixx 15. trisomy 3 copies of a chromosome 16. down syndrome result of trisomy 21 17. turner syndrome A chromosomal disorder in females in which either an X chromosome is missing, making the person XO instead of XX, or part of one X chromosome is deleted. 2/2
