Answer:d. There is no prophase during mitosis
Explanation:.during the prophase 1 of meiosis,the chromatins shortens to become chromosomes.these chromosomes double themselves and then pair up as homologous chromosomes,one from each parents.each one is called a bivalent.each bivalent is joined together at the centromere and forms a chromatid.
