Homologous chromosomes are best described by the following phrases:

1. Similar Structure: Homologous chromosomes have the same structure, with the same genes arranged in the same order.

2. Pairing in Meiosis: They pair up during meiosis, which is a type of cell division that results in gametes (sperm or eggs with half the number of chromosomes).

3. One from Each Parent: Each individual has two versions of each chromosome, one inherited from the mother and one from the father, which are homologous to each other.

4. Same Genes, Different Alleles: While homologous chromosomes carry the same genes, they may contain different versions of these genes, known as alleles.

5. Chromosome Number: They are numbered 1 through 22 in humans, with the 23rd pair being the sex chromosomes, which are also homologous in females (XX), but not in males (XY).
