Pregunta 10

Which statements are true of one single chromosome? Select all that apply.

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

Explicación

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.
