The following amongst the molecular markers is codominant in nature

Answer: Option B

SSR and RFLP molecular markers are codominant.
RFLP, as a molecular marker, is specific to a single clone/restriction enzyme combination. Most RFLP markers are co-dominant (both alleles in the heterozygous sample will be detected) and highly locus-specific.
SSRs are co-dominant markers so they can distinguish heterozygotes from homozygotes. The main advantages of SSRs are their high level of polymorphism and their reliability.
