If we take an egg from a female mouse, and two different sperms,one from male mouse and the other from male rabbit. And we perform an in vitro fertilization, and return the fertilized egg into the uterus female mouse... Question is:

Which organism will be produced and Why??

:D

none, it'll be a miscarriage or an unsuccessful fertilization.

Great answer, You are right...

But, it is the time for you to show the reason as well.. :D

dont know why??? :x :evil:
but is it because of the diagram shown ... the two sperm cells that got into the cell...

Yes, but there are other reasons than that, if you can't mention them, then I will tell you about them. :)

Mr JackBean, I like your comments, but I'm not a wise biologist


hmmmmmm, let me explain to you,,,,,

it'll be a miscarriage or an unsuccessful fertilization due to several reasons:

The sperm adapted only and only with the egg from the same species which it's belong from i.e that sperm from Rabbit can never fertilize an egg of the mouse because they not from the same species...

Deeper, both sperms will compete each other inside the egg, and everyone of them will use its enzymotic activity to delete the other one, as large number of enzymes will be released inside the egg, it will be destroyed then and fertilization will be failed.....

by in vitro fertilization you mean mix of sperms and egg or microinjection?

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

Than you should get mouse, because rabbit sperms won't be able to fertilize the egg

No, you will not get any mouse, as I told you there will be an enzymatic fighting b/t both of the sperms, and that will damage the egg preventing it to produce anything

i dont know?
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
