I noticed today that the youngest children of a family often look more like their mother rather than their father.
I thought of a few other youngest children of their respective families and realized that they almost always look more like their mother.

My theory, though it might sound a little weird, is that the older the father is when the child is had, the less the child will look like him. Why?
His sperm.
Wouldn't it make sense? Sperm gets weaker as you age. The older you are when you impregnate a female, the less likely your sperm are going to be able to pass on your genes because they're weaker.

Alert the media. Not sure if this is already a well-known fact or if I'm just imagining the youngest children looking more similar to the father, but it is something to think about.

i think it has something to do with multiple pregnancy's , partly hence the stigma of the firstborn being the cream of the crop

My little brother looks identical to my dad when he was the same age.

never made a punnett square of genetic traits?

ill get back to you in 10 years dad just had a kid and hes 52

This is just sillyness. You get two sets of DNA, one from each parent. One allele doesn't become dominant because the sperm is aging, that would mean the genetic code is decaying, which would doom humanity.

No evidence, just a random claim.



No, my idea is that the genetic code is still there, it just can't be picked up as easily.

sorry but you are wacked.... eggs, well women get so many and as they get to the bottom of the pile they are rotten....sperm on the other hand, is not stored longer than 30 days and new sperm is created, men always produce stronger traits for this reason. women and their reproductive traits will always be weaker.

Uh.... i think you need to take a middle school biology class. You get half the genes from you mother and half from your father.
