In order to answer this question, let's talk about identical twins.
00:04
It says identical twins are genetically identical, but they still are different in certain regards.
00:10
For example, one twin may develop a certain form of cancer than that the other twin may never develop.
00:16
Based on what you have got in lermitin module 2, well, you don't provide the module 2, but anyway, it says explain why identical twins are not always identical in their phenotype despite being identical in their phenotype.
00:28
So, remember that identical twins share the same dna code with each other.
00:35
Okay, and this is because identical twins were formed from the exact same sperm and egg from their father and the mother.
00:45
Usually the egg and the sperm come together and create an embryo in this, in this embryo eventually grows into a human baby.
00:54
But in case of identical twins, early in development, when you have a embryo, the sperm here you have the oxide going to produce an embryo right okay it is also known as zygote in case of identical twins early in development or well radically soon after you produce this zygote this embryo going to divide in two something like this something like this okay it's going to divide in two and this is going to create two babies instead of only one because this one does not divide it or does not divide while this one divided.
01:36
So this is how identical twins are produced from one enzyme.
01:42
But even when they share the same genes, it does not necessarily mean that they are going to be 100 % identical, okay? because our genes are more than just genes...
