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

Humans have 23 sets of chromosomes, and the sperm from the father carries one randomly selected from each set.

That gives the sperm over eight million possible chromosome selections.
