Answer:

Answer:

e. 25%

Explanation:

  • Hemophilia is inherited in the X-linked recessive pattern. This means that two recessive alleles need to be present in an affected individual.
  • Since the father is affected, his genotype is [tex]X^{h}[/tex]Y.
  • The mother is heterozygous i.e. a carrier for the hemophilia allele with the genotype [tex]X^{H} X^{h}[/tex].

Punnet Square:        

          [tex]X^{H}[/tex]           [tex]X^{h}[/tex]

[tex]X^{h}[/tex]    [tex]X^{H} X^{h}[/tex]      [tex]X^{h} X^{h}[/tex]

Y       [tex]X^{H} Y[/tex]        [tex]X^{h} Y[/tex]  

According to the Punnett square above, the probability of an affected daughter i.e. genotype [tex]X^{h} X^{h}[/tex] is 1/4 i.e. 25%.
