With the same genes for eyebrows (genotype), does the fact that someone is a female mean she will have thinner eyebrows and if a man, thicker eyebrows (different phenotype)? Or is the thickness the same, genetically determined but unrelated to gender? I know many women pluck their eyebrows which makes these look thinner and therefore the overall impression is that women have thinner brows....but for example I am female and have natural eyebrows as thick as my father's (I pluck them too of course).. So, if I have a son and give him my eyebrow genes for thickness, will he have even thicker eyebrows? Or as thick as me? For the last question, please consider my husband to have a bit thinner eyebrows than me. Thank you for any help. I'm a bit concerned my son will have extremely thick eyebrows.
