Question
- A. It means students should be able to use probability to predict the results of a single-gene cross.
- B. It means gene is never assessed in Reproduction.
- C. It means learners only need to memorise the topic title for Genetic inheritance.
- D. It means students should give the opposite of the approved learning objective.
Answer
The correct answer is It means students should be able to use probability to predict the results of a single-gene cross..
Explanation
The correct option is It means students should be able to use probability to predict the results of a single-gene cross. because it directly reflects the approved learning objective: Use probability to predict the results of a single-gene cross..
Common mistake
Misinterpreting allele frequencies
Students often assume that the probability of an offspring inheriting a particular allele is simply the proportion of that allele in the parents, without considering the number of alleles each parent contributes.
Explain that each parent contributes one allele per gene, so the probability is based on the combination of the two alleles each parent carries, not the overall allele frequency in the population.
