this topic got me looking into punnet squares again so some more science i found out it IS possible only because there are such things as hidden alleles apparently, which on a super rare chance, combine and thus the parents will have a dark haired child so luc gets off on this one.
but yeah this is a super rare chance that like most people will never see since blonde is the recessive allele meaning the parents shouldn’t be carrying any allele for dark hair bc if they did it would dominate the blonde but it seems here we tread the more complicated territory of hidden alleles (7th grade science never talks about the cool stuff)
how does Luc have black hair when both his parents had blonde hair ┑( ̄Д  ̄)┍ are they dying his hair black?? Strong family genes???
