@mrvhyte I don’t think this is an accurate definition
What would you have for the definition @braviboron? Monozygotic twins are identical vs dizygotic twins are non-identical I’m pretty sure. Are you saying like to make the definition about how many initial zygotes?
@mrvhyte sorry, you are correct. I do you think that the definition should be about number of over and number of sperm. Identical versus non identical can be in the extra.
