Answer
They are looking at a pair of homologous chromosomes attached to each other. This is the statement that best answers the question based on the information learned from today's activity. The X-shaped structure in the cartoon represents a pair of homologous chromosomes, which are two chromosomes that have the same genes in the same order but may have different versions of those genes. The fact that they are attached to each other indicates that they are in the process of undergoing meiosis, which is the cell division process that produces gametes (sex cells) with half the number of chromosomes as the parent cell.
