Question by Dan: Are sex cells from only that one cell that we are at fertilization?
Do our sex cells only carry the chromosomes from when we where first conceived and only those ones.
Since our body creates new cells from those first ones at fertilization, and those new cells could generate mutations on them.
But our sex cells do not carry thoses chromosomes and cells, they only carry the chromosomes that were present at the very first sex cell.
Is that right?
do you mean a mutation that happens in the sex cells of the zygote that were not present in the parents?

Answer by Asst Prof
Our sex cells normally carry those chromosomes from when we were conceived. Of course, the chromosomes they contain are full of recombinations, but virtually all the alleles are the same as those we received from our parents.
There may be a small number of mutations, but generally not enough to make much difference. Anything too major would result in the death of the zygote or embryo at an early stage.
