The somatic cells of Drosophila contain 8 chromosomes. Determine how many chromosomes and DNA molecules are found during gametogenesis in the nuclei before dividing in the interphase and at the end of the telophase of meiosis I. Explain how such a number of chromosomes and DNA molecules are formed.

1. A cell contains 8 chromosomes and 8 DNA molecules. This is a diploid kit.
2. Before dividing in interphase, doubling of DNA molecules occurs. (8 chromosomes and 16 DNA molecules)
3. In telophase 1, homologous chromosomes diverge to the poles of the cell, the cells divide and form 2 haploid nuclei. (4 chromosomes and 8 DNA molecules)
