1. WCH 1.120 Exam #1 F 2/16 in WCH 1.120 (bring cheat sheet) Review Th 2/15 at 5pm in GRG 102

2. haploid diploid X 23 in humans X 23 in humans X 23 in humans Inheritance = The interaction between genes inherited from Mom and Dad.

3. Do parents’ genes/traits blend together in offspring? CB 14.10

4. CB 14.3 In many instances there is a unique pattern of inheritance. Traits disappear and reappear in new ratios.

5. CB 14.6 GenotypePhenotype

6. Human blood types AA or AO AB BB or BO OO CB tbl 14.2

7. CB 14.5 Predicting the genetic future

8. Mom = ABDad = AB Inheritance of blood types

9. Human Diploid Chromosomes AB

10. Mom = ABDad = AB Gametes:A or B Inheritance of blood types

11. Mom = ABDad = AB Gametes: A or B AA ABBB AB Chance of each phenotype for each offspring 25% AA 50% AB 25% BB Mom Dad Inheritance of blood types

12. CB 14.6 PhenotypeGenotype Genes code for proteins (or RNA). These gene products give rise to traits…

13. CB 14.6 PhenotypeGenotype Genes code for proteins (or RNA). These gene products give rise to traits… It is rarely this simple.

14. CB 14.14 Single genes controlling a single trait are unusual. Inheritance of most genes/traits is much more complex… Dom.Rec. Dom.

15. Incomplete Dominanace CB 14.10

16. Human blood types AA or AO AB BB or BO OO CB tbl 14.2 Codominance

17. Eye color: One trait controlled by multiple genes

18. Human Chromosomes

19. CB 15.9 Sex determination is normally inherited by whole chromosomes or by number of chromosomes.

20. CB 15.9 X/Y chromosomes in humans

22. All humans develop as females for the first 9 weeks of development

23. CB 15.10 Sex-linked traits: Genes on the X chromosome No one affected, female carriers 50% of males affected, 50 % female carriers 50% affected, female carriers A= normal ; a= colorblind

24. Color Blind Test

25. Sex-linked traits: Genes on the X chromosome No one affected, female carriers A= normal; a= colorblind colorblind normal

26. Sex-linked traits: Genes on the X chromosome 50% of males affected, 0 % females affected A= normal; a= colorblind normal

27. Sex-linked traits: Genes on the X chromosome 50% males affected, 50% females affected A= normal; a= colorblind colorblind normal

28. CB 15.10 Sex-linked traits: Genes on the X chromosome No one affected, female carriers 50% of males affected, 50 % female carriers 50% affected, female carriers A= normal ; a= colorblind

29. CB 15.9 X/Y chromosomes in humans

30. 105 males : 100 females (live births) Why?

31. 105 males : 100 females (live births) Why?
