Investigate a unique reproductive system.
Designed for students with a more advanced knowledge of genetics, this sophisticated activity asks students to begin by determining if a gene is dominant, recessive, or sex-linked. Then they will design an experiment to test their hypothesis, including setting up a control experiment.
Once students are ready to collect their data, they will discover some perplexing facts that do not fit their hypothesis, and a Chi-square analysis should reject the sex-linked hypothesis. Eventually, students will come to realize that they are not dealing with a familiar genetic reproductive system. Instead, they are investigating a haplo-diploid system in which the males are haploid and the females are diploid.
This system will always mimic a sex-linked system since the males have only half the number of chromosomes as the females.
