Reproduction and Heredity (5-8) * Reproduction is a characteristic of all living systems. Some organisms reproduce sexually, others asexually. * In many species, males produce sperm & females produce eggs. * Every organism requires a set of instructions for specifying its traits. Heredity is the passage of these instructions from one generation to the next. * Heredity information is contained in genes, located in the chromosomes of each cell. * Some traits are inherited, others result from interactions with the environment. (NSES, 1996)

The name of this wonderful "learning tool" is called Mendel's Peas. Parts 1 and 2 (top menus, left to right) demonstrate basic principles of meiosis, fertilization, and inheritance using the same pea traits that Mendel studied. Part 3 is an application of those principles called The Princess and the Wrinkled Peas. The tool is brought to us by BioLogica. Shockwave is required. |

The name of this exceptional "learning tool" is called Zoo Matchmaker. How can zoos help save endangered species? By breeding them in captivity, in hopes of someday releasing animals back into their original habitats. This interactive places you in charge of a breeding program for endangered tigers. Choose from several breeding plans, then make the best matches to ensure tiger survival. Along the way, you'll learn about tiger genetics and the basic rules of inheritance. Presented and developed by the Minnesota Zoo. |

The name of this simple and creative "learning tool" is called Genotype to Phenotype. The tool explores the relationship between genotype & phenotype, using both sex-linked & autosomal dominant & recessive traits. By manipulating alleles (genotype), you create corresponding changes in the dragon's physical appearance (phenotype). The tool is brought to us by BioLogica. Shockwave is required. |

The name of this "learning tool" is the UNSW Embryology and is a very textured site about human embryology. The site that we link to is specifically done for K-12 students. The visuals and video on the site are stunning and very accessible. Quicktime required. This site was developed at the University of New South Wales. |
