The diagrams to answer the question are missing. However, an original set of homologous chromosomes and their sister chromatids should look like a column of one color for the homologous and another column of the same color but join with the original column by the centromere for the sister chromatid.
A chromosome is a molecule of DNA; it stores and transmits genetic information. Chromosomes have different parts and structures.
A homologous chromosome is:
- A pair of DNA molecules that have two different genetic information.
- Each chromosome comes from one progenitor. It has its respective genetic information.
A sister chromatid is:
- The replication of the homologous chromosome.
- They carry the same information.
In conclusion, an original set of homologous chromosomes and their sister chromatids will look like the one shown in the image. Two lines of a different color for the homologous chromosome and "X" of the same color for the sister chromatid, since it is a chromosome that it replicated itself and is joined to the original one by the centromere.
