How Does Chance Influence Inheritance?
Students observe how chance affects which genes appear in gametes (Mendel's Law of Segregation). They use beans to represent the recombination of alleles during fertilization.

How Does Chance Influence Inheritance?
Students complete a lab based on how chance affects which genes appear in gametes as in Mendel's Law of Segregation. They review the theories, vocabulary words, and historical background of Gregor Mendel's work with pea plants. They...

Mitosis, Meiosis and Fertilization Vocabulary Review Taboo Game
Can you describe a gamete without using the words sperm or egg? Scholars play a vocabulary review game where they try to get other players to guess their words. Each card has the target word as well as two related words they must not...

Sexual Reproduction and Meiosis
In this biology learning exercise, 9th graders label each of the diagrams representing the stages of meiosis. Then they describe how gametes vary from other cells in the body. Students also explain what happens during the process of...
