Guinea Pig Genetics tools: what they help with
These calculators predict the likely colors, patterns or morphs from a guinea pig pairing, using the known inheritance of each trait. Understanding genetics helps breeders avoid pairings linked to health problems and set realistic expectations about offspring.
What to know about genetics and morphs for guinea pigs
Guinea pigs typically live 5 to 7 years. Guinea pigs are highly social and should never be kept alone. They need a large ground-level cage, unlimited grass hay, and a daily source of vitamin C.

A practical tip
Results are probabilities across many offspring, not a guarantee for one litter or clutch. Hidden recessive genes can also surprise you.
