Will littermates and siblings have the same DNA results?Updated 2 months ago
Nope! Even though kittens and puppies of the same litter may demonstrate similar (or extremely different!) traits with each other, siblings will always have a unique DNA sequence, and therefore, different reports.
When genes are passed on to pets, each parent donates a random assortment of genes. This can result in extremely similar or extremely different genes passed on to each sibling. In addition, pets from the same litter can have more than one father! This is more common in outdoor pets and can produce an even wider array of physical and genetic traits. Basepaws can help you learn what exactly is found underneath all that fur, in each pet!
A great example of this is our CEO’s kitties, Stormy and Sunny. Although they are siblings from the same litter, Stormy is a dilute calico (female), while Sunny is an orange tabby (male). Each has a completely different personality and health history.
We also want to stress the importance of the Genetic Health Marker report for each pet. The multitude of gene variations from each parent can also result in potentially different Health Marker reports for every pet in a litter.
Do you test for sibling relationships or pet relationships?
We do not test for pet relationships at this time, whether pets are siblings or if related pets are a part of a broader family tree. We are still growing our database to make this feature possible, and we know many pet parents are eager to find out if their little ones are truly related.
If you have already tested your pets with us, and you know that they are in the same family tree, please let us know at [email protected]. With your help, we can reach this goal!
I'm not sure if I registered my pets' samples correctly, can you retest them?
Unfortunately, no, as it is the pet parent's responsibility to ensure that each pet is swabbed using the appropriate testing kit and to register each barcode correctly online to the right pet profile. Lab processing fees cost A LOT, so we cannot offer free retests for mistaken samples.
If you are confident that you swabbed your pets appropriately and registered them online correctly, it's most likely that the DNA results came by quite surprisingly due to the sheer complexity of pet genetics!
