Dog Coat Color Inheritance Pedigree

A three-generation pedigree showing autosomal recessive chocolate coat color inheritance in Labrador Retrievers. Both parents in Generation I are unaffected carriers (Bb); two of four offspring express the chocolate phenotype (bb, affected). In Generation III, an affected female bred to a carrier male produces a mixed litter.
