Elaborate Activities

Rather than your standard lesson plans, here I have added several activity ideas that are meant to elaborate on concepts students have discovered throughout a genetics unit.

Simple Genetics Activity: Human Traits Laboratory

In this activity, students will divide into groups of 4-6 and analyze their phenotypes for various traits. Afterward, they will determine their genotype and compare the similarity between the individuals in their group by filling in a trait chart. Finally, the teacher will collect data regarding the traits of all students in the class to place on the board. From this, students will analyze the frequency of alleles for their various traits within their classroom and answer discussion questions in groups. This activity is a good way not only to have students work with genetics material in a way they can relate to (their own traits), but also allows students to practice data analysis skills.

Sex-Linked Genetics Activity: Fred and Wilma

In this activy, students use information from Fred and Wilma's sex chromosomes to determine their phenotypes. In addition, they determine some of Pebble's traits (Fred and Wilma's daughter) by doing several Punnett square crosses. Here students gain practice drawing conclusions about traits and conducting data analysis on sex-linked crosses. In part II of the activity students will determine both genotype and phenotype from a set of chromosomes. Finally, they will draw conclusions regarding the inheritance of sex-linked traits in general. This activity was obtained from UNC-BEST alumni Ms. Jenny Holt. *note: making x and y chromosomes for part II of the activity is optional, but the worksheet will need to be modified
