When it comes to figuring out which traits or conditions an animal’s offspring can have, there are several different types of genes to consider. Some genetic features are easier to recognize than others. Of the many potential gene markers to look for, autosomal recessive genes often fly under the radar without proper genetic testing. Breeders who test for these conditions can provide an autosomal recessive pedigree. When understood, this can illuminate potential factors that may otherwise have come as a surprise.
What is an Autosomal Recessive Pedigree?
Generally speaking, the term ‘autosomal recessive’ refers to the characteristics of a specific genetic trait. In the context of animal breeding, an autosomal recessive pedigree means any pedigree chart that accounts for these traits.
All dogs have 78 chromosomes, which are fundamentally similar across all breeds. The specific ways these genetic sequences are expressed represent each individual’s genetic traits. Genetic traits come in many forms, and any trait dictated by a single gene marker can be either dominant or recessive. Autosomal recessive traits can be inherited from two parents carrying a specific recessive mutated gene. Because the gene is recessive, the parents are often carriers and don’t actually have the condition associated with that gene.
One trick for identifying recessive traits is that they tend to skip generations, which can be seen in pedigree charts. While this is generally true, some autosomal recessive traits don’t necessarily skip generations, depending on some other factors. The manifestation of recessive traits makes testing all the more critical. It is the only way to accurately identify which characteristics may be a part of your animal’s autosomal recessive pedigree.
Common Autosomal Recessive Traits
While the number of potential autosomal genetic traits is virtually endless, some are more impactful than others. Hip and elbow dysplasia and gastric dilation are common autosomal recessive conditions in dogs. These and other conditions can significantly affect their quality of life. Others, such as cancer, epilepsy, and congenital heart problems, are even more harmful.
Autosomal Recessive Pedigree Testing
These genetic conditions, from the most trivial to the most impactful, play a vital role in breeding. Genetic testing can reduce the chances of new dogs developing these conditions and make us aware of which traits are already present in our dogs and cats. Many diseases may never be easy to live with, but being prepared can make a world of difference in how they are mitigated and managed.
As we mentioned above, the only way to ensure your animal’s autosomal recessive pedigree is to have the right genetic testing tools and an understanding of what to look for.
