Answer 2

Dr. Foster: ‘Perhaps it might be useful if you go back to our discussion. A dominant allele has a direct effect on an individual’s appearance, whereas a recessive allele stays hidden when paired with a dominant allele, yet becomes visible when paired with another recessive allele. That aligns with what we covered in class.

Since this choice doesn’t fully capture both concepts accurately, please try another answer that might be more precise in describing why a dominant allele is observably expressed, and a recessive allele remains unseen unless it’s matched with its recessive counterpart.’

Pick another answer!

Answer 1: ‘Dominant is the allele that determines the phenotype of a characteristic even when paired with the same or different allele in the individual. Recessive has no effect on the phenotype when paired with a dominant allele because it remains hidden in that scenario.’

Answer 3: ‘Dominant is the allele that determines the phenotype of a characteristic even when paired with the same or different allele in the individual. Recessive has no effect on the phenotype when paired with a recessive allele, as it remains hidden in the genetic makeup.’
