Exercise
Form 3: Recessive Alleles & Phenotypes
In this engaging exercise, students will explore the fascinating world of genetics by investigating how recessive alleles influence phenotypes in organisms, using real-life examples and interactive activities to deepen their understanding of inheritance patterns. Through hands-on experiments and group discussions, learners will connect concepts of Mendelian genetics to observable traits, enhancing their critical thinking and application skills.
