There is no definite answer to whether a mother with an IQ problem will give birth to a mentally retarded child because the definition and measurement of IQ may differ in different cultures and social backgrounds. The IQ was an indicator of a person's intelligence quotient. However, IQ tests are controversial because they can be influenced by culture, language, and social background, and can be biased. Therefore, even if the mother had a problem with her IQ, it did not necessarily cause the child to become mentally retarded. A child's intelligence level can be affected by many factors, including genetics, environmental factors, nutrition, and education. IQ is not the only determining factor. A child's growth and development are also affected by many other factors, including family environment, social support, education, and interpersonal relationships.
