Frequently Asked Questions

How does the Gender calculator work?

It uses Mendelian genetics probability tables based on the inputs you provide for the mother, father, and grandparents.

Is this prediction a guarantee?

No, it is a statistical probability estimate. Multiple genes and genetic recombination can produce unexpected traits.
