This is the Family Genetics teaching program GeneShare. It starts with a three-generation family. 'Genotypes' are shown for 'founder' individuals (grandparents), using two 'chromosomes'. Because individuals are 'diploid', each has two copies of each chromosome.

The first aim of the program will be to fill in genotypes of other individuals in the family. Arrows are provided to navigate through the program. Click the right arrow to continue.
