Human Genetic Disorder Probabilities
In this genetic disorders worksheet, high schoolers complete punnett squares for six different human genetic disorders. They predict the outcome of the offspring including the phenotypes and genotypes of each.
Curated OER
Patterns of Heredity
High schoolers describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...
Curated OER
Biology-Genetics
High schoolers predict the probable mode of inheritance from a pedigree diagram showing phenotypes. They study the genetic basis for Mendel's laws of segregation and independent assortment. They give a Power Point slide show...

Dihybrid Cross Punnett Squares
In this dihybrid cross worksheet, students complete two punnett squares for the cross of two traits. They determine the genotypes, phenotypes and phenotypic ratios of the offspring.
Curated OER
Karyotype Puzzle
Students identify chromosome pairs based upon band patterns and location of centromere. They order chromosome pairs based upon size. Students differentiate normal karyotypes from abnormal karyotypes. They correctly record karyotype...
