I don’t get it…
Freckles are a dominant trait, but they’re rare. Am I misunderstanding something about genetics?

Any child with freckles is usually drowned shortly after birth.

Gene function, or lack there of.

A little.

The dominance of a gene has nothing to do with the rarity of the trait controlled by that gene. Dominance simply means that one variety of a gene overrides a different variety of the same gene.

If freckle gene A is dominant over freckle gene B, but the genes are only found in 1% of the population, all it means is that the children of parents are with FGA are likely to be freckled. It doesn’t necessarily mean that the entire population will eventually sport freckles, because 99% of people don’t have the genes for freckles in the first place.

RE: I don’t get it…
Yeah, dominance should not be understood here in terms of overall population frequency. What Boru said basically
"Our attitudes towards things like race or gender operate on two levels. First of all, we have our conscious attitudes. This is what we choose to believe. These are our stated values, which we use to direct our behavior deliberately ... But the IAT [Implicit Association Test] measures something else. It measures our second level of attitude, our racial attitude on an unconscious level - the immediate, automatic associations that tumble out before we've even had time to think. We don't deliberately choose our unconscious attitudes. And ... we may not even be aware of them. The giant computer that is our unconscious silently crunches all the data it can from the experiences we've had, the people we've met, the lessons we've learned, the books we've read, the movies we've seen, and so on, and it forms an opinion." - Malcolm Gladwell
