How This is Produced - There is much to explain regarding this color….
Each color found in a Pom is created by a gene. Some are dominant and will over power others…some are recessive. Merle is a dominant gene. Therefore, in order for there to be a Merle Pomeranian puppy, that pup must have at least 1 parent who carries the gene.
There is a reason why it is not a good idea for BOTH dam and sire to have this in their genetics!
2 Merles should not be bred together because there are some genetic medical issues that are associated with the relative gene. This includes hearing issues (sometimes severe), eye problems and with males, sometimes a severe reduction of the production of sperm.
