2. 4 Inherited characteristics 4 Transmitted from one generation to the next

3. 4 Offspring display the same trait as their parents

4. 4 Offspring that result when parents of 2 different pure lines are crossed

5. 4 P 1 Generation: Parental Generation 4 F 1 Generation: First Filial Generation 4 F 2

6. 4 Dominant:More common trait 4 Recessive:Hidden Trait

7. Principle of Segregation 4 1.Heredity characteristics are determined by distinct units

8. Principle of Segregation 4 2.For each characteristic, an individual carries 2 factors, one inherited from each parent

9. Principle of Segregation 4 3.The 2 factors of each pair segregate from each other and end up in gametes

10. Genes 4 Specific portions of DNA 4 Determines the characteristics of an organism

11. Alleles 4 Alternate forms of a gene that can have different base sequences

12. Alleles 4 Dominant:Capital letter 4 Recessive:Same letter but in lower case

13. Genotype 4 Two letters are needed are needed to describe each combination of alleles

14. Phenotype 4 Way an organism’s traits are expressed 4 Does not reveal the combination of allele in the organism

15. Punnet Square 4 A chart that show all possible genotype of a cross 4 Monohybrid 4 Dihybrid

16. Principle of Independent Assortment 4 The inheritance of alleles for one trait does not affect the inheritance of alleles for another trait
