if that's right....

for that doesnt that happen whenever any feertilisation takes place... be it in the body or in any other in vitro. the egg doesnt get damaged... although the enzymatic fighting is going on



Look, when only a single sperm is present, it will be the one and only whom will use its enzymatic activity, and that will not damage the egg, in additional to that, when we inject two sperms from different species will not suit the egg as their enzymatic activities are not the same, and each will try to utilize its enzymatic activity to be the one who will fertilize the egg, and due to this large number of enzymes which will be released by both of them, the egg will get damaged......

Keep in mind that, this enzymotic fighting is not regulated in both sperms... :wink:

I think you are talking about the procedure of the two sperms and one egg !! :roll:

ohh my god, :cry: that was just a question , I did not meant that I had done it before...

Yes, I did and you said:

OF course, mix of sperms and egg not microinjection...

Dear JackBean,

It is the time to open new topic and discuss in it... :D

We should close this topic and create another topic better than this.... :D

I don't know why. It is still about YOUR question for intelligent biologists

well I've a small comment as I'm not experienced But
zygot = 2n
1n frm sperm & 1n from ova

sooooooooo
n from rabbit will never = n from mouse
so they cnt complete each other to form 2n needed for fertilization
that's why different species couldn't fertilize each other
But some could as horse & donkey gives mule
different families couldn't fertilize each other but different species from samr family could

so what's ur opinion???
It's Not EASY to be anything
But
It's TOO TOO EASY to Be nothing

So Pick ur Choice

intelligent man,

You are also right...

Look, If we bring two sperms one from a dog, and the other from a wolf, and inserted both sperms into an egg of a dog female or wolf female, of course there will fertilization and one sperm only of both will fertilize the egg.... That's actually because they are both from the same family..
:D

Let me explain it!It is not that difficult!They have different number ofChromosomes
Even the sperms are able to get into the egg by means of injection,the cell core of the
sperms are not able to combine with cell core of the egg.
As we all know,a normal cell has a pair of same Chromosomes.Were they different,how
could they be able to do cell division?

@vet0lover and @chinn rod
ohk thats one consideration but what if the same specie's sex cells get fertilised instead of those from the other species...
so there are chances of having a fertiliasation that can lead to either the same speicies as thhe mother or it failing
but the answer says it just fails
i want a reason for that... for i fail to understand it...
it isn't what you do that matters but it is how you do it
