Genes are contained in chromosomes, which are mainly in the cell nucleus.
A chromosome contains hundreds to thousands of genes.
Every human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.
A trait is any gene-determined characteristic and is often determined by more than one gene.
Some traits are caused by abnormal genes that are inherited or that are the result of a new mutation.
Proteins are probably the most important class of material in the body. Proteins are not just building blocks for muscles, connective tissues, skin, and other structures. They also are needed to make enzymes. Enzymes are complex proteins that control and carry out nearly all chemical processes and reactions within the body. The body produces thousands of different enzymes. Thus, the entire structure and function of the body is governed by the types and amounts of proteins the body synthesizes. Protein synthesis is controlled by genes, which are contained on chromosomes.
The genotype (or genome) is a person’s unique combination of genes or genetic makeup. Thus, the genotype is a complete set of instructions on how that person’s body synthesizes proteins and thus how that body is supposed to be built and function.
The phenotype is the actual structure and function of a person’s body. The phenotype typically differs somewhat from the genotype because not all the instructions in the genotype may be carried out (or expressed). Whether and how a gene is expressed is determined not only by the genotype but also by the environment (including illnesses and diet) and other factors, some of which are unknown.
The karyotype is the full set of chromosomes in a person’s cells.

Walking is a well-balanced form of exercise for most people, regardless of age. Many people are able to maintain a modest level of fitness through a regular walking program. Walking is relatively easy on the joints. When walking, which of the following can strain joints?
