Scientific & Clinical Inquiries (FAQ)
How is KRT75 alpha-keratin defective curl inherited in Gallus galluss?
The KRT75 alpha-keratin defective curl follows classic Mendelian inheritance. Carriers with a single recessive allele typically appear normal but pass the mutation to 50% of gametes.
What is the danger of breeding two heterozygous carriers together?
A carrier-to-carrier cross yields a 25% statistical risk per offspring of inheriting two mutant alleles, potentially causing lethal developmental defects or expressing homozygous health anomalies.
Can DNA testing definitively confirm these alleles?
Yes, commercial veterinary genomic panels can sequence the specific locus to eliminate guesswork before pairing breeding stock.
