Somatic rabbit cells contain 44 chromosomes. How will the number of chromosomes and DNA molecules in the nucleus change during gametogenesis before the start of division and at the end of the telophase of meiosis I? Explain the results in each case.

1) before the start of division, the number of chromosomes is 44, and the number of DNA molecules is 88;
2) at the end of the telophase of meiosis I, the number of chromosomes is 22, DNA molecules are 44;
3) before the start of division, the number of chromosomes does not change, and the number of DNA doubled due to replication;
4) in the telophase of meiosis I, the number of chromosomes and DNA decreases by 2 times, since meiosis I is a reduction division
