OK, this has nothing to do with Genetics.
Or does it?
All my life I tied without realising for the most part I did so left-handed while being ambidextrous in some tasks. It was my friend Pete, that finally pointed this out to me (thanks mate) when first he saw the tying sequences in this website in 2006. He failed to mention it when we used to tie flies at the same table in the 80s. I’m not exactly sure where my ‘both handedness’ came from but find it is limited to the realm of fly-tying and DIY for the most part. Is this genes at work or a learned behaviour I wonder.
Either way, the upshot of my way of tying was the sequences I published were catering for the minority; a situation appreciated by the left-handers and subsequently mentioned in some kind emails. Of course I was concerned to cater to the whole community, so decided to duplicate all said pages with flipped images. This I hoped was good for readers, but proved hard work for me.
Then along came new technology and I’m now able to program my pages so a reader can switch the images at will, from left to right and vice-versa. It works just fine saving me time and reader’s bandwidth. The only characteristic I wonder about, is where photos show me cutting materials; sometimes I’m working the tools right handed and sometimes left. I think this is OK. I hope so.
Anyway, long live both handedness!
