13. Karyotypes

14. Karyotypes Humans have 46 chromosomes in normal body cells Karyotypes show chromosomes in pairs lined up from biggest to smallest

15. Karyotypes can tell us sex and chromosomal diseases like Down’s syndrome Karyotypes

16. chromosome Karyotype

17. Sex/gender is determined by sex chromosomes (X and Y) XX: female XY: male Karyotypes

18. Having the wrong number of chromosomes gives you a Down’s syndrome = trisomy 21 = Down’s syndrome is caused by disease An extra 21st chromosome nondisjunction Karyotypes Nondisjunction = chromosomes don’t separate when the egg or sperm is made, so there is the wrong number of chromosomes

19. Practice What disease does this person have?

20. What caused this disease? Practice

21. What sex is this person? Practice

22. Practice

23. Genetic Disorders

24. Down’s Syndrome

26. Triple X Syndrome (notes) Triple X Syndrome = females with an extra X chromosome (XXX)

27. Klinefelter's Syndrome Man with an extra X. (XXY) The principal effect is reduced fertility

28. Turner’s Syndrome Female with only one X chromsome (X) Sterile, overweight

29. Think: Karyotypes What chromosomal combinations produces a male? Female? How many chromosomes are found in a typical human cell? Down’s syndrome patients have ___x copies of chromosomes 21.
