Teaching sex linked inheritance can be tricky since students need to write both the chromosomes and the alleles. Make life a little easier with this set of sex linked practice problems. Each practice problem explains the inheritance and provides scaffolding for students to first write the genotypes of the parents, then do the punnett square and finally answer the questions. This provides students with the structure they need at first to complete multistep problems. Examples included are colorblindness, hemophilia and calico cats. There are 9 problems total.
