Mitosis diagram
Specification Link
This genetics diagram is used for: Describe how observations of chromosome behaviour in cell division supported inheritance ideas.
What To Explain
DNA is organised into genes and chromosomes, so the diagram should be linked to inherited information.
Exam Answer Move
This is aligned to: Describe how observations of chromosome behaviour in cell division supported inheritance ideas. The learner should connect the visual to genetic information, inheritance or variation as required by the objective.
Karyotype diagram
Specification Link
This genetics diagram is used for: Describe how observations of chromosome behaviour in cell division supported inheritance ideas.
What To Explain
DNA is organised into genes and chromosomes, so the diagram should be linked to inherited information.
Exam Answer Move
This is aligned to: Describe how observations of chromosome behaviour in cell division supported inheritance ideas. The learner should connect the visual to genetic information, inheritance or variation as required by the objective.
Chromosomes and alleles (2) Allele 1 Allele 3 Allele 2 diagram
Specification Link
This genetics diagram is used for: Explain that genes were later understood to be located on chromosomes.
What To Explain
DNA is organised into genes and chromosomes, so the diagram should be linked to inherited information.

Hemorrhoids Internal hemorrhoids External hemorrhoids diagram
Specification Link
This digestive system diagram is used for: Describe how observations of chromosome behaviour in cell division supported inheritance ideas.
What To Explain
Digestive organs and enzymes break large insoluble food molecules into smaller soluble molecules that can be absorbed.
Exam Answer Move
This is tied to: Describe how observations of chromosome behaviour in cell division supported inheritance ideas. The learner should explain digestion, enzymes or absorption.
