An Excess of Nonsynonymous Differences Between the FOXP2 Sequence of Humans

question 150

Multiple Choice

An excess of nonsynonymous differences between the FOXP2 sequence of humans and that of chimpanzees implies that:

• A)FOXP2 encodes a highly conserved transcription factor.
• B)the function of the transcription factor encoded by FOXP2 has been under positive selection in the human lineage but that the expression pattern of the FOXP2 gene (when and where and in what amounts the gene is expressed)has not.
• C)the expression pattern of FOXP2 (when and where and in what amounts the gene is expressed)has been under positive selection in the human lineage but that the function of the transcription factor encoded by FOXP2 has not.
• D)the function of the transcription factor encoded by FOXP2 has been under positive selection in the human lineage. No inferences regarding the effect of positive selection acting on the expression pattern of the FOXP2 gene are possible based on these data.
