[bulkimporter_image id=’5′]

To better understand the genetics of your guinea pig’s size, it’s important to consider how breeding plays a role. Genetic mutations are responsible for size variation in guinea pigs and can occur naturally or be selectively bred for. These mutations affect genes that control growth and development, leading to variations in size among individuals.

One such mutation is called the ‘dwarf’ mutation. Guinea pigs with this mutation have shorter limbs and overall smaller bodies compared to their non-dwarf counterparts. This mutation is inherited in an autosomal recessive manner, meaning that both parents must carry the dwarf gene for it to manifest in their offspring.

Another genetic factor that influences size variation is polygenic inheritance. Multiple genes contribute to determining the final size of a guinea pig. Each gene has a small effect on its own, but when combined, they can result in significant differences in size between individuals.

It’s important to note that while selective breeding can be used to achieve desired sizes in guinea pigs, it should always prioritize the health and well-being of these animals. Breeding should be done responsibly by knowledgeable individuals who understand the potential risks associated with certain genetic mutations.
