Why is the Full Coat pattern inherently less frequent in litters compared to the solid Red color?
Answer
It is associated with the recessive allele *A*t, requiring both parents to carry the gene.
The Full Coat pattern is associated with the recessive allele *A*t, meaning that for a puppy to manifest this look, both parents must carry this recessive gene, naturally decreasing its frequency in a litter.
