The correct answer is option 1: Genes. Hereditary characteristics are primarily passed on from parent to offspring through genes. Genes are segments of DNA that contain information for specific traits. They are located on chromosomes, which are found in the nucleus of cells. During reproduction, gametes (sperm and egg cells) are formed, and they each carry a set of genes from the parent. When the gametes fuse during fertilization, the genes from both parents combine to determine the traits of the offspring. Enzymes, option 2, are proteins that facilitate chemical reactions in the body and are not directly involved in passing on hereditary characteristics. Option 3, gametes, is correct as they carry the genes from the parents, but it is not the primary, or only, means of passing on hereditary characteristics. Option 4, centrosome, is not involved in hereditary characteristics and is therefore incorrect.
