This learning resource focuses on the role of sexual reproduction and meiosis in creating genetic diversity within families and populations. Students will engage in a variety of activities, including a warm-up exercise where they analyze a family portrait to identify visible traits, leading to discussions about heredity and individuality. Through guided exploration, learners will hypothesize about the factors that contribute to unique individual profiles, despite shared parentage. Key concepts such as meiosis, gamete formation, and the contrast between asexual and sexual reproduction are introduced, emphasizing how meiosis leads to genetic variation. Additionally, the concept of independent assortment and its relevance to genetic combinations is highlighted. The lesson concludes with an exit ticket task, asking students to articulate how meiosis serves as a primary source of genetic variation.
