Goodie..your little Goodie is GORGEOUS! he reminds me of Rick Astley (no offence intended..he is cute too, IMO). Does he have brown eyes? my aunt is a redhead with brown eyes, and I think it is really attractive.
Right, here is my experience of ginger genes.
My grandad and all his family were ginger. My gran was very dark haired. They produced 6 children ~ only one (my mother) was dark haired. The others were all brown/auburn coloured.
His son (my uncle) married a brown haired woman. Bearing in mind that he too had brown hair ~ they produced two boys with shocking ginger hair. No other ginger haired babies have been born to the others. In fact one of my uncles (brown haired) married a redhead and their daughter is platinum blonde.
I married a ginger haired man. He was the first ginger in two generations. Both his parents had dark hair. We have produced two children ~ both blonde.
I would say the ginger gene is pretty much a rogue..it seems more likely to skip generations and turn up unannounced ;o)
