There are two genes in the V Locus. The most dominant is V and the most recessive is v.
~ Non-Vienna V is called the Non-Vienna gene. This gene can be homozygous or heterozygous. This gene creates the normal color that is seen in all colors except Blue-Eyed-White (BEW). Some of the colors that have the Non-Vienna gene are as follows: All varieties except Blue-Eyed-White (BEW). Non-Vienna can carry Vienna. Non-Viennas that carry the Vienna gene are called Vienna Carries (VC). ~ Vienna v is called the Vienna gene. This gene can only be homozygous. It cannot carry any other gene as a recessive gene cannot carry a dominant gene. This gene masks all other genes leaving the coat white and turning the eyes blue. Some of the colors that have the Vienna gene are: Blue-Eyed-White (BEW) ~ Incompletely Dominant (Vienna Marked, Sports) When the Non-Vienna gene is paired with the Vienna gene the animals will often have white markings with their regular color. Some of the time the markings are similar to Dutch markings but, sometimes they just have white spots in different areas. The reason for this is because the Vienna gene is incompletely recessive to the Non-Vienna gene so, that when it is paired with the Non-Vienna gene sports are the result. Vienna Marked animals or Sports have the following genotype, Vv. Sometimes these sports will not show any sport markings but, a lot of the time they do. |
