Why do so many people think we came from sperm

We came from the egg... If you take an egg and look into it there's parts in there. It's like a seed, you put water on it and it starts to grow, thus starting from the egg/seed. The sperm determines the sex, the egg is the blank canvas person.

Your brain and heart is in the egg too...


No but we are inside the egg, not sperm. The sperm just helped us grow, like the water and the seed

You are right that the egg has a larger cell body than the sperm, and that it also carries certain organelles (for example mitochondria). When the sperm fertilizes the egg its largest contribution is the DNA it carries, and the chromosomes do come together inside the egg. The sperm does not just determine the sex of the fetus though, it carries half of the all chromosomes needed to produce a zygote. A seed is more like a baby or a fetus than it is like an egg, because even in plants a type of sperm is needed to make the seed.

An unfertilized egg does not have a brain and heart inside it, but it does have half of the information the cell needs to start making them.



Wikipedia has an overview of both human and plant/animal fertilization in quite a bit more detail if you are interested:

Half of out chromosomes (26) are in the egg, and half in the sperm, so technically, they are both parts of a whole. Our brain/hearts aren't even developed yet when the egg is fertilized, once the woman is pregnant, the organs begin to grow. Eggs and sperm are both single celled, so they don't have organs, but smaller structures that function in different ways, called organelles.

The sperm determines if you're a girl or a boy, depending which chromosome it contains. It also gives you a lot of your characteristics, personality, and other things. It contains 50% of your DNA. Now, if you'd like to become more educated on this subject, maybe you should learn more about genetics.

Irv S is right, we are NOT inside the egg and it is much more complicated than watering a seed. You need exactly one egg and exactly one sperm to get together for fertilization.

Both are necessary because half of chromosomes come from egg and half of come from sperm also the sperm is that which determine our sexulity not the egg. Its not just like watring a seed its more complicated.

Look closer honey.
It's about half and half as far as the gene make-up goes.
The egg has a bit of an edge when it comes to the mitochondrial DNA,
but that's about it.

Dearie, don't call people idiots who understand a subject far FAR better than you do.

You have seemed to answer your own question....
