What is sex linkage?Males have the genotype XY
whereas females are XX.
Create a genetic diagram to show the possible genotypes
produced.
What are the phenotype ratios.

Objectives Outcomes3: Describe sex linkage and some associated conditions
5: Explain fully how sex linked conditions can be inherited.
7: Evaluate the role of the X and Y chromosomes in the
inheritance of named examples of inherited conditions.
Key terms: sex linkage, haemophilia, colour blindness, inheritances.
