Genetic differences are individual physiological and psychological differences caused by genetic genes. Modern genetic science shows that there are 23 pairs of chromosomes in each nucleus of a normal human body, with a total of more than 50,000 genes that can determine the different hereditary traits of the offspring. The main component of a gene is a chemical called DNA. DNA undergoes two steps of transcription and translation, controls protein synthesis, and stores, replicates, and transmits genetic information.
