Scottish Fold
Osteochondrodysplasia
Discussion Point
History
Disease
Current Problem
Genetics
~Mating two homozygous individuals will result in 100% folded ears
~Mating a homozygous and heterozygous individual will result in 100% folded ears
~Mating two heterozygous individuals will result in 25% homozygous dominant, 50% heterozygous, and 25% homozygous recessive. 75% of litter will have folded ears.
Testing for osteochondrodysplasia is unnecessary because the folded ears is a clear indication of its presence. Testing and X-rays only come in handy to determine the severity of the crippling as the cat ages.
Homozygous recessive- fd/fd
Homozygous dominant- Fd/Fd
Heterozygous-Fd/fd
