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!!

As others have said, hair color isn’t a simple case of dominant vs. recessive. In fact, very few traits follow those simple rules of Mendelian genetics, but that’s the way most high schools explain genetics to keep the concepts digestible for beginners. Most traits involve multiple genes that have complex interactions, and it can be hard to predict the outcome.
