does each spermatozoon contain different DNA material?

Question

what im trying to ask is, would I be the same person I am, would I have the same personality, would I be so damn good looking(haha, just kidding), if another spermatozoon had "made it to my mom´s....."?????

you can give your religious view too, no problem, but please try to be as scientific about it as you can, as I still haven´t found any truth in any religion(actually im pretty sure that it´s all a bunch of bull....)

thanks

"Any particular reason why you're slamming religion...? Feeling superior...?"

it´s not about being superior... if you want to believe in santa claus or whatever it is that you believe, you are free to do that, but count me out!!

Answer 1

Think it through. If all sperms from the same man were identical, then presumably all eggs from the same woman would also be identical. Thus, you and all your brothers or sisters would be identical.

It doesn't take any religious belief or viewpoint to say that even then, background radiation or cosmic ray impacts could damage the sperm or egg, and result in mutations.

(If such a particle strike were to result in a beneficial mutation, then in order to be intellectually consistent I would have to seriously consider the likelihood that the particle was precisely aimed and guided to reach the gamete it did for that purpose. In fact, if such a thing ever happened, I think I would be FORCED to conclude that the particle was aimed or guided on purpose, but that isn't what you asked.)

Considering the fact that there are plenty of carcinogenic chemicals out there, and that they find their way into our parents' bodies long before we are conceived, I think we are all pretty lucky to be here. Even if all sperms and all eggs of individuals were identical, carcinogens and other chemicals could still cause quite a bit of variation to occur-- not necessarily healthy variation.

We are all lucky to be here. I don't see any reason this necessarily impinges on religion. Any particular reason why you're slamming religion...? Feeling superior...?

Answer 2

Hahaha. Interesting question.. Really. The answer for the question is yes.. As long as your father have the gene "handsome", (even if he didn't look good), you can still have the possibility of being "handsome"... (NB: Remember that handsome is sooo subjective.. hehe)

Each spermatozoon have different DNA according to meiosis.
Meiosis make it possible that you have a recombination with the other Sequence of DNA, so that they will be different in each spermatozoon.. So, The real problem is, how much you have the possibility to be "looking good".. And don't forget, there are many factors from the outside that can affect you too... XD

Answer 3

I honestly don't know the final truth, but an educated guess would be that they (sperm) are *mostly* the same as the male parents original DNA but some would have small differences due to gene mutation.
Differences in chromosome content are classed as a kind of 'sperm heteromorphism' by the way.
Oh yes, and lets not forget that sperms are divided 50/50 into x and y chromosome "replicas" (x would make a male, and y a female, all eggs are y - only sperm differ in this respect) so therefore if a different sperm had entered the egg there would have been a roughly 50% chance not of a small difference in your 'phenotype', but that you'd have been born as a member of the opposite sex!!!

ps to Ellen (below), I was editing my answer just as you were posting.

Answer 4

lol the answer is yes. well kind of. each sperm cell carried half of your dads characteristics but they will all be similar. the way 23 chromosomes match up with your moms 23 will define your characterisitics. But if you have siblings none of them are exactly alike. Similar but not exact copies.

Answer 5

you could have been XX instead of XY (assuming you're a guy now)
