Red hair is recessive trait, non red is dominant character. At which marriages we can expect 100% probability of red-haired children birth? When we can expect 50% and 25 probabilities of red-haired children?

parent one rr parent two rr   100%

parent one Rr parent two rr   50%

parent one Rr parent two Rr    25%

Explanation:

I have literally no idea don't take this answer lol

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.
