Legend for German Shepherd Gene Study
  White Carrier
  Black Carrier
  Blue Carrier
  Liver Carrier

The German Shepherd Gene Study tracks the recessive "masking" white
and recessive black genes forward through the generations.

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent. Often, it is impossible to determine which two alleles of a gene are present within an dog's chromosomes based solely on the outward appearance of that dog. However, an allele that is hidden, or not expressed by, can still be passed on to that dog's offspring and expressed in a later generation.

German Shepherds can carry one or both of the recessive white "masking" and/or the recessive black gene.

(A masking gene masks the real color and pattern of the dog. The only way the gene can be expressed in some of the offspring is if both parents carry it. For example, when a white dog is bred to a non-white dog that does not carry the white gene, none of the offspring will express the white coat but they will be carriers of the white gene. If those offspring are bred to a white, some of their offspring will express the white coat color. White bred to white will always produce white offspring.)
