Genetic Crosses with 2 Traits with Rabbits
Beginning biology students can struggle with dihybrid crosses and setting up Punnett squares that have two traits. When tackling this concept, make sure students are familiar and competent with basic genetic crosses and setting up Punnett squares for a single trait. For example, a tall (Tt) plant is crossed with a short plant (tt). Once…

Practice Genetics: Sex Linked Genes
Students learn basic Mendelian genetics by crossing traits from fruit flies and pea plants. In this extension, students can practice doing crosses that involve sex-linked traits, where the alleles are located on the X chromosome which affects the pattern of inheritance. This worksheet is designed for beginning biology students, as it provides in most…

Modeling Independent Assortment & Dihybrid Crosses
Students examine how two traits are inherited, revealing that each allele has an equal chance of being passed on to the next generation, the principle of independent assortment.
