Answer 2

You can expect 100% red-haired childbirth if a purebred recessive parent and a purebred recessive parent are crossed together. You can expect 50% red-haired childbirth if you cross a purebred recessive parent and a hybrid parent. You can expect 25% red-haired childbirth if a hybrid parent was crossed with a hybrid parent.
