Sexually reproducing organisms inherit their genetic sequences from both parents
Homologous chromosomes are chromosomes that share:
- This means that these organisms will possess two copies of each chromosome (one of maternal origin ; one of paternal origin)
- These maternal and paternal chromosome pairs are called homologous chromosomes
Homologous chromosomes are chromosomes that share:
- The same structural features (e.g. same size, same banding patterns, same centromere positions)
- The same genes at the same loci positions (while the genes are the same, alleles may be different)
