    So, only the sex cells go through meiosis. But, homologous chromosomes line up during the meiosis. My Q is are the sex cells themselves diploid then? It seems that way. Because the sperm and egg are haploid and they themselves can not go thr' cell division.

    Is this correct?

    From what you're saying, yes, germ cells are diploid. These are the spermatagonium and oogonium.

    The "sperm" and "egg" do end up haploid and are then gametes.

    Ok. So the germ line cells are diploid themselves. They undergo meiosis to form 4 haploid cells; sperm in males and ovary in females.
