Austrian Monk in the Czech Republic Mendel worked in the ________________ Mendel worked with _________________ Mendel studied the ___________________ of pea plants Mendel observed the ___________________________________ Biology - Chapter 11

2 Genetics Genetics: ______________________________________________________ Heredity: ________________________________________________________________________ Traits: ________________________________________________________________________ Example: the pea plant’s seed shape, color, height, flower position Biology - Chapter 11

3 3 reasons why Mendel studied genetics
Mendelian Genetics 3 reasons why Mendel studied genetics He selected the pea because of its _________________. Example: flower color, seed color, seed shape He knew from prior experiments that ____________________________________________ Pea Plant was ___________ Biology - Chapter 11

4 Biology - Chapter 11

5 Pea Plant Traits Biology - Chapter 11

6 Pea Plant Flower Biology - Chapter 11

7 Mendelian Genetics Fertilization: ____________________________________________________________________________________________________________________________________________ True-Breeding: _________________________________________________________________________________________________________ Biology - Chapter 11

8 Mendel’s Experiment Gregor Mendel studied garden peas. Pea plants are usually self-pollinating. Self-pollination: ________________________________________________________________________________________________________________________________________________________________ These self-pollinating pea plants produced ________________________________________________________________________________ Biology - Chapter 11

9 · What Mendel found was that all the offspring were _____
Mendel wanted to see what would be the offspring of a tall pea plant X with a short (dwarf) pea plant. TT (Tall)  x tt (Short) ·    This is called a monohybrid cross ______________________________________________  ·    Mendel expected to find all the offspring to be of medium height (a blending of tall and short plants.) ·    What Mendel found was that all the offspring were _____ ·    Mendel concluded that we have _________ (called (____) that control each trait.  Biology - Chapter 11

10 TT (Tall) x tt (Short) Biology - Chapter 11
    _____________________________________________ (alleles).  Example: tall and short TT (Tall)  x tt (Short) Biology - Chapter 11

11 Mendel’s Monohybrid Cross
Mendel concluded that we have two factors (called (_______) that control each trait.    ·    Each of these genes can be expressed in different forms (________).  Example: tall and short Biology - Chapter 11

12 Genetic Terms Gene – ____________________________________
Allele – ___________________________________ Dominant allele – ______________________________________________________________________________ Recessive allele – _____________________________________________________________________________________________________________________ Biology - Chapter 11

13 Laws of Genetics Law of independent assortment – ____________________________________________________________________________________ Law of segregation – __________________________________________________________________________________________ Biology - Chapter 11

14 Laws of Genetics Law of dominance – ______________________________________________________________________ Probability – ______________________________________________________________________ Punnet Square – _________________________________________________________________________________________________________ Biology - Chapter 11

15 Laws of Genetics Monohybrid cross – ____________________________________________________________________________________ Dihybrid cross- ____________________________________________________________________________________ Test cross – ______________________________________________________________________________________________________________________________ Biology - Chapter 11
