    Does that mean the dad/husband looks like he could be their brother? Or is that not how these genetics work?

      Yeah, genetics is more complicated than that. Recessive genes/traits means that while half of genetic material (discounting that X an Y chromosomes are different sizes) comes from each parent, their kid’s appearance is not just having all traits be midway between their parents’ appearances. And there’s more complications than recessive genes like epiginetics, environmental factors, multi-gene traits, etc.
