A pair of homologous chromosomes consists of
- A
Two chromosomes carrying entirely unrelated genetic information
- B
Two identical sister chromatids joined at a single centromere
- Ccheck_circle
One chromosome from each parent, with the same genes (possibly different alleles)
- D
Two chromosomes from different species sharing similar genes
Explanation
Homologs carry the same gene loci in the same order — one of maternal, one of paternal origin.
