Crossing cats with COI > 12.5% introduces steep penalties for hemophilia, dwarfism, and sterility. Boost room Comfort to 12+ or use outcrossing stray partners to dilute ancestral overlap while retaining valuable dominant alleles.

Frequently Asked Questions
How does the Breeding Calculator compute the Coefficient of Inbreeding (COI)?
The calculator uses Wright’s Coefficient of Inbreeding formula: COI = Σ (1/2)^(n1 + n2 + 1), evaluating all common ancestral generation paths. Full-sibling crosses evaluate to 25% COI, half-siblings to 12.5%, and first cousins to 6.25%.
What is the effect of Room Stimulation on kitten stat inheritance?
In Mewgenics Patch v0.14.2, base stat inheritance is a 50/50 roll between parents. High Room Stimulation increases the probability to inherit the higher parent attribute up to 90% at Stimulation 10+.
How can I prevent lethal genetic disorders during close breeding?
Keep pairing COI below 12.5% whenever possible. If breeding close bloodlines, furnish the room with Comfort >= 12 items (velvet beds, heated pads) or equip Cryo-Genetic Gene Stabilizers to reduce defect chances by up to 75%.
