In fact, it is easy for a person who is rational, as demonstrated in your blog. But not every individual is rational. I am actually wondering which proportion of young people looking to pair with someone is actually considering the genotype issue.
Personally, I was not even thinking about this when I was younger, as I was not even aware of it.
