**Step-by-Step Text Solution:** 1. **Definition of Homologous Chromosomes:** Homologous chromosomes are pairs of chromosomes that have the same size, shape, and structure. They are similar in genetic content but may carry different alleles for the same genes. 2. **Characteristics of Homologous Chromosomes:** - **Same Size and Shape:** Homologous chromosomes are identical in length and overall structure. - **Genetic Similarity:** They contain genes for the same traits, but the alleles (variations of a gene) may differ. For example, one homologous chromosome may carry an allele for brown eyes, while its homologous partner may carry an allele for blue eyes. ...
