Blonde hair and red hair are recessive traits, meaning that they require two homozygous recessive alleles to be expressed (in this case, bb or rr). What hair color would the child of a blonde and redhead have since there is a 100% chance of them being br? Would one recessive allele dominate over the other? Are there real life examples of blonde + redhead and what were the resulting children?
I am absolutely not a scientist/geneticist so please be correct any factual inaccuracies I may have made!!

I believe the term often used for such hair is “strawberry-blonde”.
Of course genetics isn’t as simple as many of us were taught in school, and variations that you wouldn’t expect can occur. My brother is blonde – but a few red hair often would show up in his beard if he grew it out enough. He isn’t “strawberry-blonde” though. One of our GREAT-grandparents supposedly had red hair (but all we have are black and white photo’s).
