Final answer:

In metaphase I of meiosis, there would be 28 chromatids in a dividing diploid cell.

Step-by-step explanation:

In metaphase I of meiosis, the homologous chromosomes line up in the middle of the cell. Each chromosome consists of two sister chromatids, so the number of chromatids is twice the number of chromosomes. Since the haploid number of the species is 14 and a diploid cell has twice the number of chromosomes as a haploid cell, the diploid number would be 2 x 14 = 28. Therefore, there would be 28 chromatids in metaphase I of a dividing diploid cell.

Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II.
Meiosis I like mitosis is the cell division that produces diploid cells. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.
