Which of the following is a dominant marker?

✏️Explanation:
-RAPD markers are dominant markers, meaning that a single copy of the amplified allele is sufficient to produce a visible band on a gel. This is because RAPD relies on the presence or absence of a particular DNA sequence that can be amplified by a short, random primer. If the sequence is present, a band will be produced, regardless of whether the individual is homozygous or heterozygous for that sequence.

✏️Other Options Explanations:
-Option B: RFLP (Restriction Fragment Length Polymorphism) markers are co-dominant markers. Both alleles in a heterozygous individual will be detected as distinct bands on a gel.
-Option C: SSR (Simple Sequence Repeat) markers are also co-dominant.
-Option D: AFLP (Amplified Fragment Length Polymorphism) markers are dominant markers, similar to RAPD.
