Answer:
The correct answer is - she is heterozygous for a mutated BLM allele and will have an increased risk of colon cancer.
Explanation:
Autosomal recessive disease expresses itself in next-generation only if there is both alleles are recessive for the gene. In haploinsufficiency, the dominant allele fails to express itself in the phenotype due to insufficiency. So, if even one allele of the recessive gene present in the haploinsufficiency case, it will affect and express its trait.
She is heterozygous for a blood syndrome, as her mother had but her father has no disease, allele and will have an increased risk of colon cancer.

He wondered how each island came to have its own type of tortoise.
