Predicting Inherited Traits
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
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
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?
