2. iNTRODUCTION
Genetics: The study of genes, heredity and variation of inherited characteristics.
Gregor Mendel which is “Father of Genetic” seeks to understand the process of
inheritance.
Genetic polymorphism: A difference in DNA sequence among individuals, groups or
populations
EXAMPLES OF MORPHOGENETIC TRAITS
 GENES AND BITTER TASTE
 DIMPLE: THE DELIGHTFUL DEFECT
 ACHOO SYNDROME

3. SIGNIFICANCES
 Better understand ourselves and improve our
health.
 Know the frequency of distribution of
morphological, genetical and behavioral traits
among people.
 Recognize the present of diversity in a
population.
 Appreciate the uniqueness in each of us.

4. GARDEN PEA EXPERIMENTS
1856-64
Mendel disagreed with the
“Blending Theory” of
inheritance.
Started with 34 kinds peas
Pisium sativum
After 2 years he had 22
purebreds

5. Mendel's Laws of Inheritance
• Law of Segregation during gamete
formation allele pairs separate or segregate,
into different gametes (Demonstrated with a
“test cross”).
• Law of Independent Assortment
suggested that each allele pair segregates
independently of other gene pairs during
gamete formation (Demonstrated with a dihybrid cross).
