Blue for more or less the same reason. You could make a lot more than 10 million if you could go back to the (for me) early 90's with insider knowledge of what's going to happen (Intel, Microsoft, Apple, Google, Amazon, Tesla, etc.) ... heck, you could be a multi-multi-millionaire if you could go back to 2009 with knowledge of Crypto. Buy a few hundred £ worth of Bitcoin in the first few months of its existence and sell it in 2021 = instant £100 million+

BUT biology is so full of infinite possibility that even if you engineered it so that you'd have kids with the same partner - they wouldn't be the same kids.

So I think this is a no-brainer for most people with kids... if you choose red, you're writing them out of existence .

Maybe some people have crap kids I guess.
