High School Biology Department: "Each Displays Its Uniqueness" - 10th Grade Homing Pigeon Trait Challenge

May 16, 2025

On May 14, the Grade 10 biology class conducted a homing pigeon trait competition in the B1 Theater of the Zhongxing Building. This activity aimed to evaluate students' abilities through diversified methods. The important content of "alleles and traits recombination" in G10 biology was fully reflected in this activity.



Within the time limit, students needed to use two sets of chromosome models in different colors and tools like scissors and tape to simulate homing pigeons’ meiosis - a crucial process of forming sperm and egg cells. During the meiosis process, the students gradually presented key stages like synapsis and crossing-over in prophase I, separation of homologous chromosomes and independent assortment of non-homologous chromosomes in anaphase I, and centromere splitting in anaphase II.


Subsequently, students randomly selected one from their two sets of self-made "gametes" to combine, simulating the fertilization process. Finally, based on the resulting offspring's genotype, students needed to distinguish the offspring pigeon's traits and paint these traits on paper. During trait determination, due to epistatic interactions between different genes, some students made some mistakes in trait judgment, but through peer discussion, they ultimately reached correct results.









It's worth mentioning that some students, while maintaining scientific accuracy, further optimized the pigeon's appearance, making the final painting better-looking. This fully demonstrated students' awareness of combining scientific and artistic elements.







The High School Biology Department is actively exploring innovative evaluation systems. Teachers create immersive learning experiences for students through diversified assessment methods like experimental operations, research projects, and presentations. In future teaching activities, biology teachers will continue to ensure objective, rigorous evaluation standards that comprehensively reflect students' overall abilities.
