Helping dog breeders combat inherited diseases through understanding genetics.

Exercise: The Inheritance of coat colour in Labradors

Use this interactive to find out about the inheritance of coat colour in Labradors. You can experiment by breeding Labradors with the three main coat colours; yellow, chocolate and black.

The genetic profiles of the puppies are randomly generated from the parents, just like in real life. Only one puppy is created at a time — create 8 to 12 for an average-sized litter.

You should have read and understood the Introduction to inherited characteristics and Labrador coat colour sections of this web site before using this interactive.
