Genetics counselors assess individual or family risk for a variety of inherited conditions, such as genetic disorders
and birth defects. They provide information and support to other healthcare providers, or to individuals and families
concerned with the risk of inherited conditions. They work in university medical centers, private and public hospitals, and physicians' offices. They work with families, patients, and other medical professionals. Most work full time and typically need a master's degree. The

Sickle cell disease is an inherited blood disorder that affects red blood cells. Since it is a recessive disorder, a
person inheriting two sickle cell genes will have the disease, whereas a person inheriting only one sickle cell gene
will be healthy, but will carry the sickle cell trait. If both parents have the sickle cell trait, and it is equally likely
whether a parent passes on the gene for sickle cell trait, determine the
1. an offspring will have the disease. ["0.25", "0", "0.5", "0.75", "1"]
2. an offspring will have the sickle cell trait. ["0.5", "0.25", "0", "0.75", "1"]
3. an offspring will have neither sickle cell anemia nor the sickle cell trait. ["0.25", "0.5", "0", "0.75", "1"]

- We sometimes hear that getting married is good for your career. Assume the table presents data from one of the studies behind this generalization that classifies men ages 18 and over according to marital status and annual income. We include only data on men to avoid sex bias.

- A study examined the interactions in a children's museum. (Interactions by visitors to the museum included show-and-tell, learning, teaching, refocusing, participatory play, advocating, and disciplining interactions.) Researchers observed a sample of 180 meaningful interactions, of which 86 were led by children and 94 were led by adult caregivers. Complete parts a through d below. a. Give a point estimate of the true proportion of all meaningful interactions in a children's museum that are led by children. The point estimate is. (Type an integer or decimal rounded to three decimal places as needed.)arrow_forwardConstruction and building inspectors ensure that construction meets local and national buillding codes and ordinances, zoning regulations, and contract specifications. They spend considerable time inspecting worksites, alone or as part of a team. Most work full time during regular business hours. Many states and local jurisdictions require some type of license or certification. The median annual wage was $56,040 in May 2014.
