Which statement best describes the limitations of using of humans in genetic studies of developmental biology?
A)The variation in human development between individuals is too large for genetic studies.
B)It is impractical and unethical to conduct experimental manipulation or targeted mutagenesis of humans to examine the role of genes in development.
C)It is impractical and unethical to examine and describe abnormalities of human development, such as birth defects.
D)Genetic studies of human development are not necessary, because most problems in human development are due to environmental influences and not genetics.

Question

Quizplus · Accepted Answer

Experimental manipulation or targeted mutagenesis, which are common practices in genetic studies of developmental biology in model organisms, are impractical and unethical to perform on humans. This significantly limits the direct study of gene function in human development.
