The genotype of the individuals is found below.

Males are XY while females are XX. Males only need one recessive allele to become affected. Thus:
- affected males will be
while unaffected males will be 
- affected females will be
, unaffected females will be
or 
Following these rules, the genotypes of individuals in the figure will be as follows:
-
2.
3.
4.
or

6.
7.
8.
9.
or
