Human males are much more likely to have hemophilia than human females. This is the case because: (3.2.2)

• the gene for hemophilia is carried on the Y chromosome

• hemophilia is a contagious disease to which males are more susceptible

What type of inheritance is shown in the pedigree below? (3.2.2)

• autosomal dominance

• codominance

• incomplete dominance
