Question

In children that express recessive genetic diseases, it has been occasionally found that only one parent is heterozygous for the disease allele. In these cases, it has also been confirmed that the parents are the true biological parents of the affected child. Which explanation best accounts for this if the father is the carrier? Select all possibilities.

THE QUESTION IMPLIES THAT ONE PARENT IS HETERZYGOUS(FATHER), AND THE OTHER PARENT IS HOMOZYGOUS DOMINANT(MOTHER).
