PHYSICAL DEVELOPMENT OF AN ADOLESCENT

-GENETIC FOUNDATIONS-

Physically adolescents are still influenced by their inherited genes. Whether or not a particular characteristic is expressed is often determined by our genotype. For physical genetic formation to take place any of the three may have contributed to a full grown adolescent.

Imprinting – A chemical marker that may activate either the Father’s or Mother’s genes.

Mutation – Sudden or permanent change in a DNA segment. Some by chance, some by environmental hazards.

Polygenic inheritance – Defined height, weight, intelligence, personality, blood pressure etc.

A girl’s body undergoes changes in fat distribution. Whiskers for Boys mark its appearance as well as the obvious mass gain for a firmer body.

Because of their sensitivity and modesty about their bodies adolescents have an increased need for privacy.

-CHANGES IN MOTOR DEVELOPMENT, SENSES and BODILY SYSTEMS-
