Investigating Human Heredity
kit #1270
An excellent introduction to the science of genetics, this enjoyable Lab-Aid contains four simple and easy-to-follow investigations.
Students study selected human traits that are controlled by a single pair of genes and then expand that study to include their lab partners, classmates and family members. The investigations begin by having students determine their phenotypes for several traits. Then, they determine genotypes for these same traits.
In the next investigation, they interpret the genotypes of individuals in a pedigree. Finally, they construct a pedigree diagram for a single inherited trait in their family by means of a controlled experiment for that trait. The students discover relationships between dominant and recessive traits. All the activities deal with easily studied inherited traits making this a highly motivating series of lab activities.
