Do all sperm cells with the same chromosome create the exact same baby?

Question

Let’s say you have two sperm cells with an X-chromosome, and one egg from the mother. If one of the sperm cells penetrates the egg it creates a baby, but if the other penetrates the egg, does it create the exact same baby, or is there a slight variation? Meaning will they e.g. look exactly the same or look a little bit different?

Answer 1

Not just different sperm, but even the exact same sperm cell and egg cell, if given multiple chances, would never create the exact same baby.
