I mean, technically he's right that the egg is the mass of tissue that becomes the body, while the sperm just wiggles in there and mixes its genetic material with the egg's genetic material. But I thought we already all knew that.
Technically, that's not correct either, for a human being. It may be correct for a bird or amphibian egg however.
An egg is one cell, a tissue is composed of many cells. An egg (a haploid cells) does not become a tissue without fusing with the sperm first. They together form a diploid cell that will be able to grow, feed, replicate DNA and then divide.
The fact that a human egg brings a bit more material than the sperm becomes irrelevant once the dividing cell starts taking nutrients from the mother's womb to build the embryo. It's not like the bird's egg, which comes with all the nutrients needed for the chick to form.
The fertilized egg is a cell that multiplies itself until it becomes the human body. That's all I'm saying. I'm not agreeing with the OP, but if we're gonna educate him, no need to make fun of the part he has right, which is that an egg is huge compared to a sperm. An egg has a nucleus, while a sperm IS a nucleus with a tail.click to expand
