The passing of traits from parents to offspring is known as heredity, therefore, genetics is the study of heredity. This introduction to genetics takes you through the basic components of genetics such as DNA, genes, chromosomes and genetic inheritance. ... Heredity is what makes children look like their parents.

Genes are segments of DNA that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Humans and all other living things have DNA, which contains hereditary information. The information in your DNA gives your cells instructions for producing proteins. Proteins drive important body functions, like digesting food, building cells, and moving your muscles.

Traits are your observable characteristics. Many physical traits are genetic. Genetic differences give our bodies information that result in traits that differ from person to person. We can also use genetic information to determine what inherited traits you may have.

Genes are small segments of DNA that have different functions. Many, but not all, genes make the proteins that our bodies need to function. You have two copies of each gene, one on each chromosome in a pair.

Genes are packaged into tightly wound lengths of DNA called chromosomes. Humans have 23 pairs of chromosomes. Sex chromosomes, identified as X or Y, determine whether a person is male or female.
