B. Establishing     1. Lesson Purpose
   Lesson Purpose       In a city hospital, a mix-up of the most curious kind unfolded. Daddy Willy
                          and Mommy Celia welcomed their newest addition, Baby Volty with short
                          fair skin, into the world. But instead of joy, confusion reigned supreme.
                          Mommy Celia was convinced of a hospital blunder, alleging their baby had
                          been swapped. Daddy Willy, a homozygous for his dark skin, and Mommy
                          Celia, heterozygous with a history of fair-skinned relatives would like to
                          know if indeed Baby Brandy is their child. How can you help them?
                          Guide Question:
                              1. How can you help solve the problem of Daddy Willy and Mommy
                                 Celia?
                              2. How can you predict the characteristics of an offspring of an
                                 organism?
                    2. Unlocking Content Area Vocabulary
                        Let students read the story in Activity 4.1: "The Colorful Tale of Bella,
                          Benny, and Their Butterfly Brood: A Story of Genetics and Diversity"
                                                                 3

                          Instruct students to highlight or mark terms that are related to genetics
                           and describe what they mean. The following are some words to unlock:
                              a. Genotype: The genetic makeup of an organism, consisting of the
                                 alleles it inherits from its parents.
                              b. Phenotype: The observable traits or characteristics of an organism,
                                 resulting from its genotype and influenced by environmental
                                 factors.
                              c. Homozygous: Having two identical alleles for a particular gene
                                 (e.g., homozygous dominant or homozygous recessive).
                              d. Heterozygous: Having two different alleles for a particular gene
                                 (e.g., one dominant and one recessive allele).
                              e. Genotypic Ratio: The ratio of different genotypes produced by a
                                 genetic cross, representing the probability of each genotype
                                 occurring among the offspring.
                              f. Phenotypic Ratio: The ratio of different phenotypes produced by a
                                 genetic cross, representing the probability of each phenotype
                                 occurring among the offspring.
                          Ask the following guide questions:
                              a. Which words are related to genetics?
                              b. How are these words important for predicting the trait of an
                                 offspring?
C. Developing and   Day 2
   Deepening        1. Explicitation
   Understanding        Let students Accomplish the Activity 4.2: My Future family. This activity
                          will allow students to visualize the characteristics of their future children.
                          In effect, it will give them an idea in predicting traits of their own
                          offspring.
                          Facilitate a classroom discussion about the activity.
                           Guide questions:
                              1. What traits would you like your children to have? From your future
                                  wife or husband? Why?
                              2. How will you predict if such traits will be inherited?
                                                                  4

Day 3
2. Worked Example
    Introduce Punnett squares as a tool for predicting offspring genotypes and
      phenotypes in genetic crosses.
      Model how to set up and use Punnett squares using examples related to
       the trait studied in the pedigrees.
      Discuss the dihybrid and monohybrid cross.
      Clarify any misconceptions and ensure students understand the
       difference between genotype and phenotype.
      Let students accomplish Activity 4.3: Patterns of Inheritance
      Assign groups to present their work in class and check students' answers.
Day 4
3. Lesson Activity
    ● Provide each group with a different genetic cross involving the trait studied   Teachers are encouraged to
      (e.g., homozygous dominant x homozygous recessive).                             provide their genetic problems
                                                                                      on mono and dihybrid crosses.
   ●   Instruct students to predict the genotypic and phenotypic ratios of the
       offspring using Punnett squares.
   ●   Encourage students to discuss their predictions within their groups and
       justify their reasoning.
   ●   Have each group present their predictions to the class and facilitate a
       discussion comparing and contrasting the different crosses.
