this. genes are genes.

What do you mean picked up as easily? That means nothing. For a gene to NOT work, it would have to be either damaged or permanently turned off. If you did this for the entire half coming from the genetic code from the father, the zygote wouldn't even live long enough to split once.

vouche....depending on whos cream its made of anyway.

This has probably already been posted in this thread, but here's my take:

Sperm, regardless of how old the father is, are replenished on a consistent basis. Sperm do not "age". One consideration would be the possibility that the DNA contained within the sperm's head has mutated due to the father's age. The mechanisms behind gamete production may deteriorate over the years, but I highly doubt that it would affect the ability for the DNA to contribute to the zygote. Mutations are more due to chance or environmental factors than age, as far as I'm concerned.

As most people know, in simple terms, you get half of your DNA from your father, and half of your DNA from your mother. Your mother gives an X chromosome, while your father gives you either his X or Y chromosome. If you got anything other than XX or XY, you would be born with some kind of mental or physical deformity (or not at all) and would be less likely to look like one of your parents.

I think this notion of "the youngest children of a family often look more like their mother rather than their father" is some kind of biased observation you've made, rather than a scientific trend.

Hope that helps.

Biochem/biotech ftw.

Genetic code does degrade with each successive replication because the lagging stand needs an RNA primer to replicate from the 5' to 3' end. Although telomeres do help preserve from some degradation.

Thats not the same sense as the OP used decaying. He's talking about turning all the genes inherited from the father recessive to the mothers genes.

interesting theory i have seen this too

and those genes and their development depend on other factors, like the validity and strength of the donors products [eggs and sperm]. You are an idiot.

Dude, take a high school biology class. Find me ANY circumstance where a males sperm fertilizes an egg but is so badly damaged it doesn't express genes in the offspring.

If the sperm isn't strong enough to reproduce, they don't have viable offspring. It takes two to tango. If one set of DNA isn't viable you get a bloody mess on a tampon.

@Lims shoot me a pm sometime
