Probability of having a male child with the disorder =

Figure 6 shows the inheritance of a genetic disorder in a family.

Person 7 and person 8 plan to have another child.

Determine the probability that the child will be a male who has the disorder.

You should:

• draw a Punnett square diagram

• identify the genotype of person 7 and the genotype of person 8

• identify the phenotype of each offspring genotype

• use the symbols:

H = dominant allele

h = recessive allele
