This is one of the reasons you see a higher standard deviation for traits in female birds than male birds. The opposite of humans.

- nicoburns 8y agoAm I correct in interpreting your comment as saying that human women generally have less variance in (gendered?) traits than human men. That's an interesting observation if it is what you meant.
- Nasrudith 8y agoWell part of it is also that any X-linked traits are more likely to tend dominant with the back-up copy. Look at colorblindness for one. Women would need a 'bad' gene on both Xs. A man would lack a backup copy on the Y and thus only needs one for it to express.
- JamesBarney 8y agoYeah you see it in a couple of traits like height, etc.. Basically it's if you have a gene on the x chromosome that increases height by an inch in a man, it will only increase a woman's height by half an inch. And vice versa with removing an inch.
