The mother is heterozygous for the syndrome, hence let us assume her genotype to be XX, while the man is normal, hence his genotype will be XY. Their children will have following genotypes:

Gametes	X	X
X	XX = normal daughter	XX = carrier daughter, phenotypically normal
Y	XY = normal son	XY = affected son

Hence, there is a 0% probability of the yet to be born female baby to be afflicted with the disease.

Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons...

Excess Thyroxin-binding Globulin (ETG) is a thyroid disorder that is inherited with the X-linked dominant allele E. The X-linked recessive allele e does not contribute to ETG. Short index finger, where the index finger is shorter than the ring finger, is a sex-influenced autosomal trait that is dominant in males and recessive in females. Let allele S1 be for short index fingers and allele S2 be for long index fingers. The inheritance pattern for this trait is shown in the...
