Part C
If the woman has a daughter with a man who does not have OTD, what is the chance the daughter will be a heterozygous carrier of OTD? What is the chance the daughter will have OTD?



100% chance to be heterozygous carrier of OTD, 0% chance to have OTD.
50% chance to be heterozygous carrier of OTD, 0% chance to have OTD.
50% chance to be heterozygous carrier of OTD, 25% chance to have OTD.
100% chance to be heterozygous carrier of OTD, 50% chance to have OTD.
50% chance to be heterozygous carrier of OTD, 50% chance to have OTD.
