Does meiosis and mitosis (or both) end with unreplicated chromosomes? which begins with replicated chromosomes?

Mitosis ends with replicated chromosomes. Meiosis is the splitting of gametes (idk if I spelled that right) and crossing over occurs in prophase 1, so by the end the diploid cells have different chromosomes and by the end of the second splitting the haploid cells are a mixture of the chromatids from the diploid cells.
