Answer: The A and B genes are dominant
Explanation:
Active genes are found in the EUCHROMATIN of eurkaryotic chromosomes.
Euchromatin is a type of chromatin which is composed of DNA, RNA and proteins and which is enriched with active genes. Euchromatin is the most active portion of the genome inside the cell nucleus. For humans, 92% of their genome is made up of euchromatin.
