Lol it took me decades. But I didn't read anything about genetics until really 5 or 6 years ago and I still read as little as I can.
I learned it as I went so it was just in bits and pieces with whatever I was breeding at the time. It's fascinating and I doubt I'll ever come close to knowing nearly everything.
I can imagine it would seem overwhelming to start from scratch and have so much info readily available a click away.
Idk I would think the key is to take baby steps. Learn something and then build from that instead of seeing the whole picture and expecting just to jump in and learn it all.
On my Christmas list.
