Your DNA and Chromosome Patterns

The most common patterns appear to be 46 chromosomes and an XX sex chromosome  (female) and 46 chromosomes plus an XY chromosome (male). A chromosome is a piece of coiled DNA (deoxyribonucleic acid), two long, twisted strands that contain complementary genetic information, like a picture and its negative (double helix). Tiny, tiny, tiny—but immensely powerful. It appears that 99 % of all the DNA in the human body is found in the chromosomes.
