Form 14: Animal Traits Genetics

In this engaging exercise, students will explore the fascinating world of genetics by observing and recording various traits in animals, allowing them to understand inheritance patterns and the role of DNA in determining physical characteristics. Through hands-on activities and real-life examples, learners will enhance their critical thinking skills while discovering how genetics shapes the diversity of life on our planet.
