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.

I love freckles

don't have them but the wife and earlier girlfriends all had red hair and freckles
(prolly not a coincidence)

What Are Freckles, Why Do They Appear, and More

[GrandizerII]

Yeah, dominance should not be understood here in terms of overall population frequency. What Boru said basically

Redheads with freckles are hot 😍
