Predicting Inherited Traits

预测遗传性状

Description

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

Mastery Evidence

✓ Defines allele, dominant, and recessive in the context of inheritance
✓ Constructs a Punnett square for a monohybrid cross and calculates probability ratios
✓ Explains the difference between genotype and phenotype
✓ Gives an example of a human characteristic controlled by dominant/recessive alleles

Assessment Prompt

If your child 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?
