Your question is not very explained but heredity causes a person to go through puberty if that's what you're talking about
Through meiosis, diploid parents produce haploid cells called gametes. The gametes, through sexual reproduction, then meet and join into one cell called a zygote that is diploid.
The zygote then develops into a diploid organism with genetic traits from both parents.
