How does a zygote differ from a mature egg? a zygote has more chromosomes.
00:06
A zygote is smaller.
00:07
A zygote has multiple cells, or a zygote divide by meiosis.
00:12
So an egg cell, a mature egg, is a gamete.
00:17
It contains half of the parent's genetic material, and the goal of that is sexual reproduction.
00:23
So this egg is going to fuse with a sperm cell.
00:26
So it puses with a sperm cell to form a zygote.
00:34
And the zygote is the first cell of a new individual.
00:38
And it will divide and divide, and you will get fetal development, and eventually you will get a new individual.
00:48
So what's the difference? is a zygot smaller? no.
00:54
So a zygot is not really much bigger than an egg, because a sperm cell is so tiny in comparison, they're really about the same size.
01:03
Does a zygote consist of a modern one cell? no, not yet.
01:07
A zygote will divide into multiple cells, but zygot is the name for that very first cell.
01:14
Does the zygote divide by meiosis? no...
