1. First, it's important to understand what homologous chromosomes and chromatids are. Homologous chromosomes are pairs of chromosomes, one from each parent, that are similar in shape and size. Each chromosome in a homologous pair carries the same genes in the same location, but the specific versions of those genes might be different.

2. A chromatid is one of two identical halves of a replicated chromosome. During the S phase of the cell cycle, each chromosome is replicated to produce two identical copies, which are called sister chromatids.

3. So, if a cell has 5 pairs of homologous chromosomes, that means it has 10 chromosomes in total.

4. At the start of mitosis, each of these 10 chromosomes would have been replicated during the S phase of the cell cycle. This means that each chromosome now consists of two identical sister chromatids.

5. Therefore, a cell with 5 pairs of homologous chromosomes would have 20 chromatids at the start of mitosis.
