Question

If a parent has genotype Aa, he transmits either A or a to an offspring (each with 1/2 chance). The gene he transmits to one offspring is independent of the one he transmits to another. Consider a Parent with 3 children and the following events: A={children 1 and 2 have the same gene} B={children 1 and 3 have the same gene} C={children 2 and 3 have the same gene}. Show that these events are pairwise independent but not mutually independent.
