  • Q:

    Gene duplication events are common drivers of increasing complexity in organisms. How might selective pressures on such genes be different from the selective pressures on the original gene?

     

    A

    Selective pressures on the new gene would be stronger because mutations on the gene are more likely to be deleterious and costly to the organism

    B

    Selective pressures on the new gene would be weaker because mutations in the new gene would not likely affect the organism since the original gene is still present

    C

    Selective pressures on the new gene would be stronger because mutations in the new gene would not likely affect the organism since the original gene is still present

    D

    Selective pressures on the new gene would be weaker because mutations on the gene are more likely to be deleterious and costly to the organism
