Sagot :

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.
