A chromosome is one strand, a replicated chromosome has two sister chromatids. Homologous chromosomes are two similar, but not identical, chromosomes that together have four strands.
- unreplicated chromosome-1 strand - replicated chromosome-2 strands - together, the 2 strands is a chromosome - each strand is a sister chromatid - Homologous Chromosomes-2 similar chromosomes (not identical)-4 strands
