  1. It carries exactly one gene
  2. It carries many different genesالإجابة الصحيحة
  3. It is shorter than a single gene it carries
  4. Each of its genes sits at its own fixed positionالإجابة الصحيحة

الشرح

One chromosome is long enough to hold a great many genes, and every one of those genes has a set place along its length, which is why matching chromosomes carry the same genes in the same order. The one-gene idea would need a separate chromosome for every gene, and a chromosome cannot be shorter than something contained within it.
