Question

Quizplus · Accepted Answer

The fact that the gene for "Abcde" is expressed in Demetrius' phenotype regardless of his father's contribution suggests that it is dominant. This means that if Demetrius had inherited a recessive gene for the same trait from his father, the dominant "Abcde" gene would still be expressed. A protein is a molecule, not a gene, so choice B is incorrect, and meiosis is a process of cell division, not a gene, so choice D is also incorrect.
