These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.

• partial: Explain how alleles are inherited in sexual reproduction and use Punnett squares to predict the probability of offspring inheriting a characteristic, including dominant and recessive alleles

  This lesson uses only a hypothetical single-gene plant model. It does not establish a simple dominant/recessive rule for human traits or assess human eye-colour inheritance.

• partial: Defines allele, dominant, and recessive in the context of inheritance

  This lesson uses only a hypothetical single-gene plant model. It does not establish a simple dominant/recessive rule for human traits or assess human eye-colour inheritance.

• partial: Constructs a Punnett square for a monohybrid cross and calculates probability ratios

  This lesson uses only a hypothetical single-gene plant model. It does not establish a simple dominant/recessive rule for human traits or assess human eye-colour inheritance.

• partial: Explains the difference between genotype and phenotype

  This lesson uses only a hypothetical single-gene plant model. It does not establish a simple dominant/recessive rule for human traits or assess human eye-colour inheritance.

• blocked: Gives an example of a human characteristic controlled by dominant/recessive alleles

  No one-gene human characteristic example supplied; eye colour is polygenic. Hypothetical plant cross does not fulfil this human-specific clause.

• blocked: If {{name}} was asked why two brown-eyed parents can have a blue-eyed child, could they explain what dominant and recessive alleles are and show how it works using a Punnett square?

  No one-gene human characteristic example supplied; eye colour is polygenic. Hypothetical plant cross does not fulfil this human-specific clause.
