11: Trait Inheritance - Biology
Parents pass on traits to their children. Understanding how this happens is an important and valuable skill. Blood type, cleft chin, dimples, and widow’s peaks are all inherited in a simple fashion. The inheritance of other traits is much more complex and poorly understood these traits include height, skin color, and eye color. Unfortunately, genetics also plays a role in the inheritance of some diseases such as Huntingdon’s, sickle cell anemia, and Tay-Sachs disease.
A degree in genetics can be used in careers ranging from a forensic examiner, a genetic counselor, a medical geneticist, a statistical geneticist, to a clinical technician.
Occupation Spotlight: Genetic Counselors
Genetic counselors use their understanding of the rules of heredity to help gauge the risks of genetic diseases. They may advise a couple of their risks for passing on certain genetic disorders, order genetic testing, and then explain the chances that some genetic diseases will show up in any offspring. Genetic counselors are there to help potential parents understand risk factors and the prognosis of genetic disorders, including basic treatment and management plans in the case of certain disorders.
