Based on the above information, the mutation type is frameshift mutation.
It is a genetic mutation caused by indels of various nucleotides in a DNA succession that is not detachable by three. The additions and erasures cause an adjustment in the length of a quality, which causes a movement in the codon perusing outline. A frameshift mutation happens when a protein is radically modified as a result of an addition or an erasure. Tay-Sachs illness is a human issue caused by a frameshift change.
It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. If one parent is homozygous for a recessive allele and one parent is heterozygous for a recessive allele in an autosomal dominant genetic disorder, the chance that <span>a child of those two parents will have the disorder is 75%. Hope this helps.</span>
