WebAug 15, 2024 · When two reproductive cells unite, they become a single cell that contains two copies of each chromosome. This cell then divides and its successors divide … WebFeb 4, 2024 · Since each of the parent cell’s chromosomes were replicated during interphase, there are two copies of each chromosome in the cell during prophase. Once the chromatin has condensed into individual chromosomes, the genetically-identical chromosomes come together to form an “X” shape, called sister chromatids.

WebThis occurs by undergoing DNA replication (in S phase during interphase) where the monovalent chromosome is duplicated so that it will have two DNA strands that are replicas of each other. These two strands are each now called a sister chromatid, and the two sister chromatids make up a divalent chromosome. Webhow are they different? a.
