What happens if you breed a straight-eared Scottish Fold with a straight-eared Scottish Fold? - briefly
Breeding two straight-eared Scottish Folds typically results in offspring that will also have straight ears. The genetic mutation responsible for the folded ears in Scottish Folds is recessive, so it is not expressed in straight-eared individuals.

Breeding two straight-eared Scottish Folds involves a complex interplay of genetics and inheritance patterns. Scottish Folds are known for their distinctive folded ears, which are the result of a genetic mutation. However, breeding two straight-eared Scottish Folds, which do not carry the folded ear gene, will yield specific outcomes.
Firstly, it is essential to understand the genetics behind the ear shape in Scottish Folds. The folded ears are caused by an autosomal dominant gene, known as Fd. This means that a cat only needs to inherit one copy of the Fd gene to have folded ears. Straight-eared Scottish Folds do not carry the Fd gene and thus do not exhibit the folded ear trait. When two straight-eared Scottish Folds are bred, they do not possess the Fd gene to pass on to their offspring.
The resulting kittens from such a pairing will inherit straight ears, as neither parent contributes the Fd gene. The genetic makeup of the kittens will be homozygous for the straight ear gene, meaning they will have two copies of the gene that results in straight ears. This ensures that all kittens from this breeding will have straight ears and will not carry the Fd gene.
Additionally, it is crucial to consider the health implications of breeding Scottish Folds. The gene responsible for the folded ears is also associated with a condition known as osteochondrodysplasia, which can cause skeletal issues and joint problems. Breeding two straight-eared Scottish Folds mitigates this risk, as the offspring will not inherit the Fd gene and thus will not be predisposed to these health issues.
In summary, breeding two straight-eared Scottish Folds will result in kittens that all have straight ears and do not carry the Fd gene. This breeding practice avoids the potential health risks associated with the folded ear mutation, ensuring healthier offspring. It is always advisable to consult with a veterinarian or a geneticist when planning breeding programs to ensure the well-being of the animals involved.
