Compares the processes of mitosis and meiosis, focusing on the tissues in which these processes occur, the behaviour and number of chromosomes involved and the types of cells produced. Shows actual cells undergoing mitosis and meiosis.

Uses the analogy of soccer to explore diversity in plant and animal reproductive strategies. Compares sexual and asexual reproduction, looking at chromosomal activity, genetic variation and consequences of budding, binary fission and spore production.

Outlines the principles which form the basis of classical genetics. Demonstrates the experiments that Gregor Mendel conducted on pea plants and reveals the laws of inheritance. Probability and Punnett squares predict the results of monohybrid crosses.

Uses the analogy of square dancing to introduce dihybrid crosses. Illustrates how the laws of inheritance for monohybrid crosses also apply to dihybrid crosses. Demonstrates how probability and the product rule determine the outcome of trait crosses.

Reveals how knowledge of Mendelian genetics, blood groups, and pedigrees can be used to solve a paternity case. Examines other patterns of human inheritance involving skin colour, eye colour and height.

Looks at exceptions to segregation and independent assortment during gamete formation. Examines the effect of gene linkage on phenotypic and genotypic ratios. Uses cross-over values in Sordaria to determine the distance of a gene from the centromere.

Examines the findings of Thomas Morgan regarding sex-linked inheritance. Investigates the probabilities of males and females inheriting sex-linked traits such as colour blindness and hemophilia. Uses graphics to analyse sex-linked traits.

Describes how the nervous and endocrine systems work together to maintain homeostasis and equilibrium in humans. Examines the structure of the neuron and explains the biological basis for multiple sclerosis.

Compares the cyclical patterns of reproduction in humans with that of other mammals. Describes the human menstrual cycle and the hormones that regulate it. Addresses the effects of lifestyle and aging on the menstrual cycle and explains hormone therapy.

Explores the electrochemical nature of nerve impulse conduction and transmission. Analyses the different stages of the membrane potential through simulations, discussions with a neurophysiologist and a visit to the dentist.
