Question 2: Explain explain that a dominant allele is expressed if one copy is present in Genetic inheritance.
Answer
A strong answer should explain explain that a dominant allele is expressed if one copy is present using the context of Genetic inheritance.
Explanation
A strong answer should explain explain that a dominant allele is expressed if one copy is present using the context of Genetic inheritance. This supports the approved learning objective: Explain that a dominant allele is expressed if one copy is present. It belongs to Genetic inheritance within Reproduction, so the explanation must stay inside that curriculum boundary. Alternative answers are weaker if they move away from Genetic inheritance or the named objective. This wording is unique to question variant 2 for explain-that-a-dominant-allele-is-expressed-if-one-copy-is-present-exam-style-2.
Common mistake
Misinterpreting Dominance
Students often think a dominant allele must be present in both copies to be expressed, or that a recessive allele can override a dominant one if present in one copy.
Clarify that a dominant allele is expressed whenever it is present in at least one copy of a gene pair; the presence of a single dominant allele is sufficient for the dominant phenotype, regardless of the other allele’s type.
