1. INTRODUCTION TO GENETICS By: Samantha Rose Bernardo Vanessa Celine Gabaldon AAPD2F

2. What is Genetics? It is the science that deals with the study of heredity and variation. GENETICS came from the word gen, genetikos meaning generative and genesis meaning beginning. HEREDITY : transmission of traits from parent to offspring. VARIATION : similarities and differences

3. Scientists Who Contributed in Genetics

4. CHARLES DARWIN Idea of natural evolution Origin of Species Pangenesis Theory

5. also contributed in Pangenesis Theory gemmules ARISTOTLE

6. Father of modern Genetics He used Pisum Sativum ( Graden Pea) in his study. There are 7 characteristics of pea in his study LAW: Mendelian Laws of Inheritance (Law of Segragation and Independent Assortment) GREGOR MENDEL

7. WHO DUPLICATED THE WORK OF MENDEL (1900)

8. CARL CORRENS

9. HUGO DE VRIES

10. ERICH VON ISCHERMAK

11. FRIEDRICH MIESCHER He said that within the chromosomes, there is weak acid.

12. WILLIAM HENRY SUTTON Affiliated the behavior of chromosomes to the genes.

13. SCIENTISTS WHO CONFIRMED DNA

14. OSWALD AVERY

15. COLIN MUNRO MACLEOD

16. MACLYN McCARTY

17. ROSALIND FRANKLIN Gave an idea that the structure of DNA is a helical structure.

18. SCOPE AND BRANCHES

19. CYTOGENETICS Science that deals with the physical basic of heredity (cell) MOLECULAR GENETICS Chemical basis of heredity Newest and most advanced field of Genetics

20. BRANCHES OF MOLECULAR GENETICS GENOMICS Study of genes of an organism PROTEONICS study of proteins coming from DNA replication.

21. CLASSICAL GENETICS Study of analysis of offspring to mating (parents to offspring) POPULATION GENETICS Deals with the transmission of trait with a large group of individual through a passage of time. BEHAVIORAL GENETICS Study of behavior of an organism.

22. BEHAVIORAL GENETICS Study of behavior of an organism.

23. METHODS OF GENETIC STUDY 1. Pedigree Analysis Transmission of trait through the use of pedigree. Pictorial representation 2. Karyotyping Detect chromosomal abnormality karyogram / karyotype (pictorial representation of chromosomes)

24. 3. Planned Experimental Breeding Dominant trait - can be seen and manifested trait. Recessive - hidden trait Homozygous - two identical alleles Heterozygous - two unidentical alleles 4. Twin Study Study of twins

25. Kinds of Twins: Praternal - Dizygotic twin Identical - Monozygotic twin Concordance twin ( praternal )- possess a trait or do not or both Disconcordance (identical)- if one possesses the other is not. 5. Statistical Analysis Make use of several data Use for population data

26. Null Negative guess Alternative Positive guess 2 Kinds of Hypothesis

27. GENETIC ENGINEERING Key factor for biotechnology Come up with a desirable trait Manipulating a certain trait

28. APPLICATION OF GENETICS Field of Medicine Agriculture/Food Production/Industry Legal Application Genetic Counseling Genetic Code

29. The End
