Students love this fun way to practice their knowledge of basic genetics and Punnett Squares.
This worksheet includes identifying Heterozygous vs Homozygous, Recessive vs. Dominant, and Punnet Squares.
Section 1: Students indicate if a genotype is homozygous or heterozygous from a list of 12 different combinations.
Section 2: Students are given Dominant and Recessive genotypes and students will label their phenotypes (4 different genotypes) example: Green body is dominant, pink body is recessive; what is their phenotype?
Section 3: Students are given phenotypes and must decide their possible genotypes.
Section 4-7: Students are given two parents and must decide what their children could possibly be by filling out a Punnett Square and composing percentages.
To further this assignment, you could have students draw a picture of what a child might look like from Alien A and Alien B :)
