Solution

The true statement is: "The number of genes in a cell exceeds the number of chromosomes."

Here's why:

  1. Genes are segments of DNA that carry the instructions for making proteins, which do most of the work in cells.

  2. Each chromosome contains many genes. Humans, for example, have approximately 20,000-25,000 genes but only 46 chromosomes (23 pairs).

  3. Therefore, the number of genes in a cell is much greater than the number of chromosomes.
