Science 8 Week 3

1. TO TEACHER JULIE CHANNEL

2. SCIENCE 8 first QUARTER WEEK 3 - DAY 4 Matatag curriculum Pedigree Analysis

3. Pedigree Analysis CONTENT The learners learn that Inherited traits passed from parents to offspring are governed by the rules on the patterns of inheritance. LEARNING STANDARD Describe simple patterns of inheritance in organisms. Represent patterns of inheritance of a simple dominant/ recessive characteristic through generations of a family. LEARNING COMPETENCY

4. By the end of the lesson, the 80 percent of the learners will be able to: Describe patterns of inheritance through pedigree analysis Perform the activity called Pedigree Analysis to Describe patterns of inheritance. Appreciate the significance of heredity in shaping an individual's physical and psychological characteristics by answering the guide questions. OBJECTIVES

5. C. Developing and Deepening Understanding What Are Genes? Fundamental Units of Heredity Genes are segments of DNA that serve as the fundamental units of heredity, containing instructions for the development, functioning, and inheritance of traits in organisms. Simple Definition Genes are like the tiny instructions passed from parents to children that shape certain traits or features in the children.

6. C. Developing and Deepening Understanding Gregor Mendel: The Father of Genetics Pioneer of Heredity Gregor Mendel: Considered as the Father of Genetics for his work on heredity

7. C. Developing and Deepening Understanding Dominant vs Recessive Traits Dominant A genetic trait that is expressed when present, overriding the expression of its recessive allele. Recessive A genetic trait that is expressed only in the absence of the dominant allele.

8. C. Developing and Deepening Understanding Understanding Genotype Genetic Makeup Genotype: The genetic makeup of an organism, consisting of the alleles it inherits from its parents.

9. C. Developing and Deepening Understanding Observable Traits: Phenotype Observable Characteristics Phenotype: The observable traits or characteristics of an organism, resulting from its genotype and influenced by environmental factors.

10. C. Developing and Deepening Understanding Family Genetic History 1 Pedigree Charts Pedigree: A diagrammatic representation of a family's genetic history, showing the transmission of traits across generations.

11. C. Developing and Deepening Understanding The Complete Picture of Genetics DNA & Genes Fundamental units containing hereditary instructions 1 Inheritance Patterns Dominant and recessive trait expression 2 Genetic Makeup Genotype determines observable phenotype 3 Family History Pedigrees track trait transmission across generations 4

12. Let students create a concept map on how they understand the different concepts and ideas that were discussed on heredity. Let the class present their work in class and check for misconceptions and clarify challenging ideas. (Day- 4) 1. LEARNERS’ TAKEAWAYS D. MAKING GENERALIZATION

13. Conclude the lesson with a reflection period where students can share their thoughts and insights on genetic diversity. Encourage students to consider how they can apply their understanding of diversity to future studies and careers in genetics and healthcare. Reiterate the importance of embracing diversity as a fundamental aspect of human genetics and promoting equity and inclusion in genetic research and practice. (Day- 4) 2. REFLECTION ON LEARNING D. MAKING GENERALIZATION
