A recent study showed that Alzheimer’s disease may be partly inherited.
John’s father suffered from Alzheimer’s disease. John is keen to get genetically tested to see if he will develop Alzheimer’s disease.
Explain why John’s genotype will not reveal whether he will suffer from Alzheimer’s disease.

Jemima and Lily are identical twins. Lily complains to Jemima, “I don’t understand it. If we have the same genes, how come you have clearer skin than me and are much better at netball?”
Jemima laughs and replies, “Lily, we may be identical twins, but we are not identical people.”
Using your knowledge of genotype and phenotype, explain Lily’s and Jemima’s comments.

Steph and Georgie are both working mothers.
Steph enjoys being challenged at work. Steph’s daughter listens to her mother’s colleagues praising and admiring Steph’s work and sees the awards she has been presented with in recognition of her effort. Steph’s daughter is an enthusiastic student who is keen to be challenged at school.
Georgie hates her job. Her daughter has heard her boss shout at her down the phone for missing deadlines and sees how tired Georgie is after staying up late working. Georgie’s daughter feels anxious when she is given difficult work and does not want to go to school.
In what ways might the biological approach explain the different attitudes of Steph’s and Georgie’s daughters to their schoolwork?
