Can a human sperm be fertilised by a animal egg?

Question

Since you can cross different species of animals (ie lions and tigers crossed can create ligers, horses and a donkey crossed create mules) would it be possible to cross a human sperm with a animal egg or vice versa

Answer 1

For a start - sperm fertilise eggs, not the other way around.

This is a question of taxonomy (classification). Lions and tigers are different SPECIES (tigris, leo), but are the same GENUS (Pantera). So their genes can be combined - but their offspring are infertile.

Same goes for horses and donkeys. They are both from the genus "Equus" - so they have enough genetic similarities to interbreed but again the offspring are infertile.

The only animals we would be able to interbreed with are other great apes - chimpanzees, gorillas, orangutans etc.

Answer 2

You have it backwards.
The question should be "Can a human sperm fertilize an animal egg?".
Sperm does the fertilizing,and the egg gets fertilized.
Anyhoo.....
I hope you're asking this question for the sake of science,and not out of worry for the embarassment that will ensue when a human-sheep hybrid comes knocking at your door one day wondering why you never took him fishing.
Daa-aa-aa-dy!
Not to worry.The differences between the chromosomes of species prevents the possibility of offspring such as these.
But there are examples of closely related species having offspring.
Mules are the result of horses and donkeys mating.But they are sterile,meaning that they can't reproduce by themselves.
You need more donkeys and horses to make more mules.
There are also rare cases of Tigons and Ligers.
They are the result of lions and tigers mating,depending on who the daddy is.
Forget your aspirations of building an army of "Monkey-Bats" like you saw in the "Wizard-of-Oz".
Your money would be better spent on an army of giant robots with chainsaw hands if world domination is your goal!

Answer 3

The species have to be very close to each other. As others have said, horses and donkeys are close, lions and tigers are close. Humans and other apes are not close enough. Neanderthals and their genetic material became extinct, probably because they and Homo sapiens sapiens had drifted apart genetically. Even though they would have looked very similar, any mating that took place either did not result in pregnancy, or resulted in infertile offspring, like mules. So, if species as similar as Neanderthals and modern man could not reproduce effectively, what chance do you think there is of cross species fertilization?

Answer 4

First off, eggs are fertilized by sperm not sperms fertilized by eggs.
Second, the only way you can create crossed breeds is if the genetic code is very similar. Also the two species must have the same number of genes and carry the same genes (humans have A C D T - I think) and we carry 48 genes, 24 we get from our mother and 24 that we get from our father. If there are any genetic mutations it causes genetically defects (ie. Down Syndrome).

Answer 5

No, animals don't have the right amount of chromosomes and their sperm won't be able to break into a female humans egg wall.

Answer 6

dont think it could..
