American Board of Genetic Counseling (ABGC) Boards Practice Test 2026 - Free Genetic Counseling Practice Questions and Study Guide

The carrier frequency for cystic fibrosis (CF) among African American individuals is approximately 1 in 61. This statistic reflects the prevalence of carriers within this population, which is notable because CF is often associated with a higher carrier frequency among Caucasians, typically around 1 in 25.

Understanding the carrier frequency is important in genetic counseling as it helps professionals assess the risk for recessive genetic conditions like CF. This information is particularly valuable for individuals of African American descent when considering family planning or undergoing genetic testing. The data also emphasize the importance of population-specific studies in genetic counseling, allowing for tailored risk assessments based on ethnic backgrounds.

The other options present frequencies that are either too high or low for the African American demographic, emphasizing the need for accurate statistics and the proper interpretation of carrier rates within different population groups to provide effective counseling.
