You may have seen blue nose Pitbulls, but are blue nose Pitbulls rare? Their unique nose color makes them appear different from other Pitbulls. However, there is no other difference between them except a different nose color. If you compare them with regular Pitbulls, then yes, blue nose Pitbulls are rare to find. In this article, we will tell you the reason behind this. Read the complete article if you want to find the reason.
Why Are Blue Nose Pitbulls Rare?
The blue nose pitbull puppy is born due to the homozygous recessive genes. The chances of a blue nose newborn depend upon the parents. Even both regular black nose pitbull parents can give birth to a blue nose pitbull puppy, and even both blue nose pitbull parents don’t give birth to a blue nose pitbull puppy. However, if both parents have a blue nose, then the chances of giving birth to a blue nose puppy increase. How the nose color of parents Pitbulls increase or decrease the chances of giving birth to a blue nose puppy? We’ll explain the answer with the help of a punnet square diagram.
Punnett square diagram
In the Punnett square diagram, the dominant genes are represented with the capital letters genes, and the recessive genes are represented with the lowercase letters. The common characteristics or features that are usually found in breeds are the dominant genes. For example, you will see the black nose color or the grey coat color of blue Pit. On the other hand, the unique features like the blue color of the nose are recessive genes.
Just look at this Punnet square diagram. The capital letters like A and B in this diagram represent the dominant genes. The lowercase letters like a and b are representing the recessive genes. From the diagram mentioned above, you can conclude that, after breeding, the puppy that will be born will have a nose color like this:
- Look at the first box in the diagram; the BB are representing the homozygous dominant genes. It means, there are 25% that the newborn puppy will have a pure black nose.
- Now, look at the 2nd and 3rd boxes in the diagram. Both contain Bb, which is heterozygous. It means a combination of dominant and recessive traits. The heterozygous pair in two boxes means there are 50% chances that the blue nose Pitbull will have a black nose and carry a gene for a brown nose.
- Now, look at the 4th box of the diagram. The bb in this box represents the homozygous recessive genes. It means there are 25% chances that the blue nose Pitbull puppy will have a blue nose.
Keep in mind that the percentage means every puppy’s chances; it doesn’t mean out of sixteen puppies, four must have a blue nose. We hope your mind is clear now that why blue nose Pitbulls are rare.
In comparison to regular black nose Pitbulls, blue nose Pitbulls are rare. The reason behind the rarity is that the chances of giving birth to a blue nose Pitbull are low. The only difference between these Pitbulls is the nose color. Otherwise, there is no difference between the black nose, blue nose, or the red nose Pitbulls.
