Biology students often complain about genetics. They find it difficult to understand, and are often presented with examples that don't relate to real life (who cares if the pea plant is tall or short, or if the seed coat is smooth or wrinkled, they're still peas).
Since many students are currently learning genetics at this time of the year, I thought that it would be helpful to provide a link to some online labs that can help with this sometimes challenging topic. They are also kind of fun to do if you have a good grasp of what's going on.
Parts 1 and 2 are reviews of meiosis and fertilization. Part three is a challenge involving the use of genetics to create the right types of pea plants (using the story of the Princess and the Pea).
This lab lets you test your understanding of genotype and phenotype by having you manipulate the genotypes of the dragons.
