1. Genetics Why your family is messed up?

2. Gregor Mendel Father of Modern Genetics Pea Plants Monk

3. Gregor Mendel Alternative versions of genes (alleles) account for variation

4. Gregor Mendel For Each Character, an organism inherits two alleles

5. Gregor Mendel If the two alleles are different, One is dominant and one is recessive

6. Gregor Mendel The two alleles segregate during gamete production

7. Gregor Mendel Independent Assortment

8. Sex-linked On the X chromosome Colorblindness Hemophilia Muscular dystrophy

9. Sex Influenced On a autonomic chromosome but affected by what sex you are Male pattern baldness

10. Blood Types

12. Linked Genes On a autonomic chromosomes near each other Red hair / freckles

13. Pleiotropy One gene has multiple effects Sickle-cell anemia

14. Epistasis A gene at one location alters the phenotypic expression of a gene on a second location Fur color

15. Polygenic Characters vary in a population along a continuum Skin Color

16. Recessively Inherited Traits Must inherit genes from both parents to display trait Albinism Tay-Sachs Cystic Fibrosis

17. Dominately Inherited Traits Must inherit genes from only one parents to display trait Achondroplasia Huntington’s disease

18. Fetal Testing

19. Nondisjunction Aneuroploidy

20. Human Disorders Down’s Syndrome Turner’s Syndrome Klinefelter’s Syndrome Trisomy X Syndrome

21. Cloning

22. Stem Cells A Cell that’s job has not been determined Early embryonic Stem Cells Blastocyst Embryonic Stem Cells Fetal Stem Cells Umbilical Stem Cells Adult Stem Cells

23. Stem Cells For each new application of stem cell technology, we must consider: What are the benefits? What are the risks? Whom will the technology help? Does it have the potential to hurt anyone? What does this mean for me? For my family? For others around me? Why might others not share my view?

24. Stem Cells Ethical, legal and social issues. Ethical issues are those that ask us to consider the potential moral outcomes of stem cell technologies. Legal issues require researchers and the public to help policymakers decide whether and how stem cell technologies should be regulated by the government. Social issues involve the impact of stem cell technologies on society as a whole.
