There are only 2 possible genotypes for the mother, FF and Ff.
Explanation:
Because it is an autosomal inheritance, this case F will be the dominant allele and f the recessive allele, where f produces Fatty acid metabolism disorder. If the mother does not possess the disorder, she must possess at least one dominant allele for that specific gene. However, for the other allele, we cannot assure that it is dominant, since it can be recessive and not express itself either in her or in the offspring, because of the father we also only know his dominant allele.
