Question 2: Explain explain that different forms of a gene are called alleles in Genetic inheritance.
Answer
A strong answer should explain explain that different forms of a gene are called alleles using the context of Genetic inheritance.
Explanation
A strong answer should explain explain that different forms of a gene are called alleles using the context of Genetic inheritance. This supports the approved learning objective: Explain that different forms of a gene are called alleles. 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-different-forms-of-a-gene-are-called-alleles-exam-style-2.
Common mistake
Confusing alleles with genes
Students often say that alleles are the same as genes, or that a gene can have only one allele, instead of recognising that a gene is a locus on a chromosome and that each locus can have multiple alleles.
Explain that a gene is a specific location on a chromosome that can exist in different forms (alleles). Clarify that each individual carries two alleles for a gene (one from each parent) and that the set of all possible alleles for a gene is called the allele pool. Use examples such as the gene for flower colour in pea plants having alleles for purple, white, and pink to illustrate the concept.
