Answer: The correct answer is- XbYb, XbXb, XbY
As per the question, the genotype of daughter is- XbXb.
Females have XX genotype and they transmit X chromosome to their progeny whereas males have XY genotype and they transmit X chromosome to their daughter progeny and Y chromosome to their male progeny.
In other words, a daughter inherits one X chromosome from father and another X chromosome from mother. In order to have XbXb genotype, the parent must possess the Xb chromosome.
Therefore, the three genotypes that parents must have in order form a daughter with XbXb are- XbYb, XbXb, XbY
