Question 2: Explain explain that a recessive allele is expressed only when two copies are present and no dominant allele is present in Genetic inheritance.
Answer
A strong answer should explain explain that a recessive allele is expressed only when two copies are present and no dominant allele is present using the context of Genetic inheritance.
Explanation
A strong answer should explain explain that a recessive allele is expressed only when two copies are present and no dominant allele is present using the context of Genetic inheritance. This supports the approved learning objective: Explain that a recessive allele is expressed only when two copies are present and no dominant allele 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-recessive-allele-is-expressed-only-when-two-copies-are-present-and-no-dominant-allele-is-present-exam-style-2.
Common mistake
Misunderstanding Recessive Alleles
Students often think that a recessive allele can be expressed even if only one copy is present.
Emphasize that a recessive allele is only expressed when two copies are present and no dominant allele is present.
