Kindly answer the underlined questions and provide explanation

Dear student, let us consider the cell has 14 chromosomes at the interphase. At G1 phase, there will be 14 chromosomes as no DNA replication has taken place. After S Phase, the DNA content doubles but chromosome number still remains same here 14. After completion of M phase, the number of chromosomes will be 28 with each daughter cell having same number of chromosomes as that of parent i.e 14. Thanks and regards
