German shepherd and genetics
In any complex life the genes is the fundamental material that determines the traits exhibited by that life. The traits exhibited by a pup are passed down in the genes of both parents including the solid black color of the black German shepherd.
Genes exist as a pair and each parent will contribute one of its pair to the pup to form its own pair of genes which will determines the traits of the pup in that area of the pup’s life (genotype). Not only do genes exist as a pair but dominant genes will always manifest in the pup when present (i.e. as long as one of the pair is a dominant gene) while recessive genes will only manifest if both genes that form the pair are recessive.
The black color is the default color for dogs which is also influenced by the genes. The genes that are responsible for the coat color in the GSD are the color gene and the pattern genes. The pattern genes are responsible for coat patterns in the GSDs.
Genes are responsible for the black pigment formation in the GSD but in some GSDs the black pigment formation is not allowed free expression as it is either blocked or diluted such as in the liver German shepherd and the blue German shepherd. These are usually caused by the color genes which are also recessive genes but in the case of the black German shepherd the solid black color is not due to the recessive color genes but the recessive pattern genes.
Therefore the solid black pattern gene does not affect the formation of the black pigment as it happens in the blue and liver GSDs. So the solid black pattern gene merely causes the black German shepherd to wear a solid black pattern.
