What kind of kittens will a straight-eared cat and a folded-eared cat have? - briefly

The type of kitten produced by mating a straight-eared cat with a folded-eared cat can vary. While the exact ear shape of the offspring is influenced by genetics and cannot be predicted with certainty, it is common for them to have one or both ears displaying some degree of folding.

What kind of kittens will a straight-eared cat and a folded-eared cat have? - in detail

The appearance of kittens born from a straight-eared cat (prick-eared) and a folded-eared cat (floppy-eared) is primarily determined by genetics, specifically the dominant and recessive genes that influence ear shape in felines.

In cats, ear type is governed by a single gene with two alleles: the dominant allele for straight ears (D) and the recessive allele for folded ears (d). A cat with at least one D allele will have straight ears, while a cat must have two d alleles to have folded ears.

When a straight-eared cat (DD or Dd genotype) mates with a folded-eared cat (dd genotype), the possible combinations of offspring are as follows:

  1. Straight-eared kittens: Each kitten has a 50% chance of inheriting the dominant allele from the straight-eared parent, resulting in prick ears. These kittens will have the genotype Dd.

  2. Folded-eared kittens: The other 50% of kittens will inherit only the recessive allele from both parents, leading to floppy ears. These kittens will have the genotype dd.

Therefore, in a litter resulting from this mating, you can expect approximately half of the kittens to have straight ears and the other half to have folded ears. This distribution is due to the Mendelian inheritance pattern, where each parent contributes one allele to each offspring, creating a predictable ratio of traits in the next generation.

It's important to note that while this genetic model provides a general prediction, environmental factors and other genetic modifiers can sometimes influence the final appearance of the ears. However, under normal circumstances, breeding a straight-eared cat with a folded-eared cat will result in a mixed litter with both ear types represented.
